Russian President Vladimir Putin made an announcement in February that turned fears of war into a reality for Ukrainians, sending political, economic and humanitarian reverberations around the world.

Mr Putin recognised the “independence” of Donbas, a largely separatist region in Ukraine comprising what he proclaimed to be the Donetsk People's Republic and the Luhansk People's Republic, effectively laying out the pretext for what became a deadly invasion of the former Soviet nation.

Here is a timeline from that announcement until today:

February 22

In a televised address, Mr Putin says he recognises the “independence” of Donetsk and Luhansk and sends Russian troops to act as “peacekeepers” there.

The decision comes after Moscow sent tens of thousands of soldiers to the border with Ukraine as western nations sounded the alarm over an impending Russian attack.

The move prompts the first round of what Nato describes as “massive and unprecedented” sanctions, but few envisage what is to come. These have led to an almost complete freeze on Russia's banking connections with the outside world.

February 24

In a recorded message, Mr Putin announces a “special military operation” in Ukraine and the first round of missiles aimed at targets in Ukrainian cities is launched.

US President Joe Biden begins freezing the US assets of Russian financial institutions and imposes sanctions on four Russian entities, including the Bank for Development and Foreign Economic Affairs, better known as Vnesheconombank, and private lender Promsvyazbank, along with 42 of their subsidiaries.

“These sanctions ensure VEB and PSB can no longer do business in the United States and are cut off from the US financial system,” the US Treasury says.

Ukrainian President Volodymyr Zelenskyy says 137 Ukrainian civilians and military personnel have been killed during initial fighting.

February 25

Mr Zelenskyy announces martial law and bans military-age men, those between the ages of 18 and 60, from leaving the country.

Nato says it will send an air, land and sea Response Force for defensive purposes, the first time it has announced such a deployment since its long stand-off with the Soviet Union in the Cold War, which ended in 1991.

Ukrainian Foreign Minister Dmytro Kuleba accuses Russian forces of attacking a kindergarten and an orphanage.

“We are collecting this and other facts, which we will immediately send to The Hague,” he says on Twitter, referring to the international war crimes court.

February 26

Russia launches cruise missiles at the cities of Sumy, Poltava and Mariupol, Ukrainian officials say.

Russian troops advance towards the capital as Mayor Vitaly Klitschko says a building was struck by Russian artillery.

Ukraine’s military says it repelled an overnight attack on an army base in central Kyiv, an apparent helicopter assault aimed at capturing Hostomel airport.

February 27

In another escalation, Mr Putin announces that he has placed Russia's nuclear deterrent force on alert in response to Nato’s “aggressive” statements.

The move comes after Russia and Ukraine sent delegations to the Belarusian border to start ceasefire negotiations.

In the meantime, several Russian banks are removed from the Swift interbank system, making it harder for Russian companies to do business internationally — by this point the most stringent financial measure taken against Russia by western countries.

The EU bans Russian aircraft from flying over its airspace and agrees to send weapons and equipment to Ukraine — an unprecedented move by the bloc.

“Another taboo has fallen. The taboo that the European Union was not providing arms in a war,” said the EU’s foreign policy chief, Josep Borrell.

February 28

Peace talks on the Belarusian border yield no results and the UN estimates that 520,000 Ukrainians have fled the country.

Mr Zelenskyy calls for fast-track membership of the EU “via a new special procedure” after signing an official request to join the 27-member bloc.

“I am sure we deserve this,” he says. “I am sure that all this is possible.”

Analysts say that Russia is preparing a much larger offensive on several fronts within Ukraine but there is debate over whether initial attacks failed or whether they were “probing” attacks to evaluate the strength of enemy positions.

Satellite images from commercial imaging company Maxar show large military convoys approaching Kyiv, some of which are several kilometres long.

Kharkiv, Ukraine's second city and the site of heavy fighting during the Second World War, comes under heavy rocket fire for the first time in more than 77 years.

March 1

In his State of the Union address, Mr Biden says he stands by the Ukrainian people against the Russian president who, he says, will be “met with a wall of strength he never anticipated or imagined”.

He says the US will ban Russian planes from using its airspace.

Mr Biden also says further action will be taken against Russian oligarchs in the US.

“We are coming for your ill-begotten gains,” he tells them.

Sheikh Mohamed bin Zayed, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the Armed Forces, calls the Russian president to discuss a path for a peaceful solution to the crisis “in a way that guarantees the interests and national security of all parties”.

The UK issues its first tranche of sanctions against Belarusian military targets who played a role in the invasion.

YouTube says it will block channels linked to Russia’s state-backed RT news network and Sputnik news agency across Europe, effective immediately.

March 2

The UN says that more than a million people have left Ukraine, one of the fastest mass movements of refugees this century.

At the UN, the General Assembly votes overwhelmingly to condemn Russia’s military assault on Ukraine — the latest major diplomatic setback to Mr Putin’s decision to launch an “unprovoked” war in Eastern Europe.

The US launches a task force to pursue “corrupt Russian oligarchs” and those breaching sanctions imposed on Russia.

In Kyiv, Mr Klitschko and his brother Wladimir, both former world heavyweight boxing champions, appear together to call for more support from allies to defend Ukraine against Russia. Meanwhile, heavyweight boxing champion Oleksandr Usyk says he has no fears about signing up to fight.

A Russian military convoy, reportedly dozens of kilometres long and headed for Kyiv, shows no movement in the previous 24 hours but local officials in Ukraine confirm that Russian forces have taken over Kherson city, making it the first urban centre to fall since the Russian invasion began.

In the UAE, Assistant Undersecretary for Consular Affairs Faisal Lutfi says Ukrainian citizens continue to be eligible for visas on arrival.

March 3

Zaporizhzhia, Europe’s largest nuclear power plant, comes under attack by Russian forces, causing a fire to break out. The Ukrainian authorities say the fire was put out and the plant is secure.

“According to those responsible for the plant, a training building and a laboratory were affected by the fire,” Oleksandr Starukh, head of the military administration of the Zaporizhzhia region, says on Facebook.

Russia’s military onslaught has claimed the lives of at least 227 civilians, including 15 children, the UN’s human rights chief says, with the real figure expected to be much higher.

The Biden administration announces new sanctions against Russian oligarchs and others in Mr Putin’s inner circle.

“These individuals and their family members will be cut off from the US financial system; their assets in the United States will be frozen and their property will be blocked from use,” the White House says.

Saudi Arabia's Crown Prince Mohammed bin Salman receives phone calls from Mr Putin and Mr Zelenskyy.

The UN scrambles to step up aid operations in Ukraine, as officials expect 10 million people to flee their homes. Four million alone are set to spill across the country’s borders, it says.

March 4

The Zaporizhzhia nuclear plant falls under Russian control amid global concern about the risk of environmental disaster created by the shelling of the power station.

Nato leaders hold an extraordinary meeting to discuss the alliance's response to Russia’s invasion of Ukraine. Nato chief Jens Stoltenberg rejects Ukraine's plea to impose a no-fly zone to halt Russian bombing, citing the danger of widening the conflict.

Mr Zelenskyy criticises the decision in a video released late in the day, saying it amounts to a “green light” for Russian air strikes.

In a sign of Nato's growing links with Nordic countries and concerns about future Russian aggression, non-members Finland and Sweden are invited to the meeting in Brussels.

Russia blocks Facebook and some other websites on Friday, passing a law that gives Moscow much stronger powers to crack down on independent journalism.

Foreign news outlets such as the BBC and the Canadian Broadcasting Corporation said they will suspend reporting from inside Russia out of concern for risks to their staff because of the law.

March 5

Russia announces ceasefires around the cities of Mariupol and Volnovakha to allow citizens to leave, in the first formal cessation of hostilities since its troops entered Ukraine. Officials in Mariupol say residents have been without electricity, water and heat since Russian forces surrounded the Sea of Azov port on Thursday.

March 6

The number of refugees fleeing Ukraine is expected to reach 1.5 million as Russia continues its attack. Kyiv presses for further western help, including more sanctions and weapons.

Moscow and Kyiv trade blame over a failed ceasefire that would have allowed civilians to flee Mariupol and Volnovakha. Ukrainians who can escape go to neighbouring Poland, Romania, Slovakia and elsewhere.

Ukrainian negotiators say a third round of talks with Russia on a ceasefire will go ahead, although Moscow is less definitive.

In a televised address, Mr Zelenskyy calls on people in areas occupied by Russian troops to fight.

“We must go outside and drive this evil out of our cities,” he says, vowing to rebuild his nation.

Meanwhile, Mr Biden speaks on the phone with Mr Zelenskyy for about half an hour.

The US is increasing “security, humanitarian and economic assistance to Ukraine, and is working closely with Congress to secure additional funding”, he tells the Ukrainian leader, according to a White House statement.

The US president highlights actions to raise the costs of war to Russia, and welcomes Visa and MasterCard’s moves to stop operations in Russia.

Washington works with Poland and holds discussions with other Nato allies on a plan to have those countries supply warplanes to Ukraine for use against Russian forces, the White House says.

Mr Putin repeats that he wants a “demilitarised” and “de-Nazified” neutral Ukraine, likens western sanctions “to a declaration of war”, and says: “Thank God it has not come to that.”

Seeking to mediate, Israeli Prime Minister Naftali Bennett meets Mr Putin at the Kremlin and later speaks to Mr Zelenskyy. He also meets German Chancellor Olaf Scholz in Berlin.

British Prime Minister Boris Johnson issues a six-point plan to respond to the invasion before meetings this week with leaders from Canada, the Netherlands and central Europe in London.

Turkish President Recep Tayyip Erdogan is expected to talk to Mr Putin. Turkey, a Nato member, shares a maritime border with Ukraine and Russia in the Black Sea.

March 7

Ukraine says that a Russian proposal on humanitarian corridors is “completely immoral” after Moscow suggests that it will allow people to flee Ukrainian cities, provided they exit to Belarus or Russia.

Oleksiy Arestovich, an adviser to the Ukrainian president's chief of staff, says each Ukrainian should be allowed to decide where they want to go but advises them against moving to Russia.

He says negotiations are taking place with Russia on establishing humanitarian corridors but that they are unlikely to be set up while Russian forces keep trying to advance.

As many as five million Ukrainians are expected to flee the country if Russia's bombing continues, the EU's Mr Borrell says.

We will need more schools, more reception centres, more of everything

Russian forces continue their offensive, shelling the city of Mykolaiv, 480 kilometres south of Kyiv, Ukraine’s defence officials say. Rescuers say they are putting out fires in residential areas caused by rocket attacks.

Shelling also continues in the suburbs of Kyiv, including Irpin, which was loses electricity, water and heating for three days.

Police in Russia detain more than 4,600 people at nationwide protests against Mr Putin's invasion of Ukraine, according to an independent protest monitoring group. Russia's Ministry of Interior says 3,510 have been detained.

Russia's rouble tumbles to a record low in thin offshore trade.

The US House of Representatives explores a bill that would ban the import of Russian oil and energy products, a move that could add to economic pressure as more companies pull out of the country.

Oil prices rise to just shy of $140 a barrel after the White House says it is considering an embargo on Russian crude imports.

As Russian forces pound Ukrainian cities with rockets despite announcing a ceasefire to allow civilians to flee some areas, lawyers representing Kyiv and Moscow will speak on Monday at the UN's top court in a legal bid to bring the devastating war to an end.

The International Court of Justice is opening two days of hearings at its headquarters, the Peace Palace, into Ukraine’s request for its judges to order Russia to halt its invasion. Ukraine is scheduled to present its arguments on Monday morning, with Russia set to respond on Tuesday.

March 8

The UN says that Ukraine's refugees are expected to top two million as intense fighting continues.

“I do think that we will pass the two million mark today or maybe, at the latest, tomorrow. So, it doesn't stop,” Filippo Grandi, the UN High Commissioner for Refugees, tells reporters in Oslo.

On Monday, the UNHCR puts the number of refugees at more than 1.7 million. Mr Grandi says that it is the first time Europe has reported such a wave since the Second World War.

After several failed attempts, Russia promises to open humanitarian corridors on Tuesday to allow civilians to flee from Ukrainian cities that have come under artillery fire.

Buses packed with people fleeing the Russian invasion in Ukraine begin a procession along a snowy road out of one city on Tuesday as a new effort to rescue civilians along safe corridors finally begins.

The route out of the eastern city of Sumy is one of five promised by the Russians to offer civilians a way to escape the Russian onslaught.

Earlier on Tuesday, Ukraine's Deputy Prime Minister Iryna Vereshchuk confirms the humanitarian corridor for civilians to flee the city will be organised and a ceasefire will be declared on the route at 9am Kyiv time.

The Russian Defence Ministry also says a ceasefire will be observed from 10am Moscow time and humanitarian corridors will be open from Kyiv, Chernigov, Sumy, Kharkiv, and Mariupol.

Previous attempts to lead civilians to safety amid the biggest ground war in Europe since World War Two have crumbled with renewed attacks.

Fast-food chain McDonald's announces that it will temporarily close all 847 of its restaurants in Russia, including its Pushkin Square location, increasing pressure on other global brands to pause operations in the country.

The closures will carry symbolic importance. When the first McDonald's restaurant opened in Russia, in central Moscow in 1990, it became a symbol of flourishing American capitalism as the Soviet Union fell.

McDonald's says it will continue to pay salaries to its 62,000 employees in Russia. Because of its large size and global reach, the chain is often copied by other brands if it takes a stance on an issue or makes a major operational change.

“If they decide to do something, then probably others will follow,” said international franchise consultant William Edwards.

March 9

Russia again offers to provide humanitarian corridors in Ukraine to enable civilians to leave five cities after several attempts to establish safe exits failed.

Ukrainian officials said Russian shelling made it impossible for people to use the corridors, despite a deal being reached a day earlier.

The Russian military counters the claim, alleging Ukraine only allowed civilians to use one corridor from the city of Sumy and blocked other routes from Kyiv, Chernihiv, Kharkiv and Mariupol.

Russian Col Gen Mikhail Mizintsev says the Russian military has announced it will stop firing to allow people to leave safely via the corridors.

He suggests setting up a hotline between Russia and Ukraine to coordinate the evacuation.

March 10

International leaders join Ukraine in decrying Russia's “barbaric” attack on a children's hospital in the besieged city of Mariupol.

Mr Zelenskyy calls the “direct strike” a “war crime” but Russia's Foreign Ministry accuses Ukrainian “nationalist battalions” of using the hospital to set up firing positions after moving out staff and patients.

In Washington, the House of Representatives votes 414-17 to impose a ban on imports of Russian oil and other energy products. It earlier advanced about $14bn of aid for Ukraine.

The foreign ministers of Russia and Ukraine prepare to hold face-to-face talks in Turkey, where Mr Erdogan, who has pushed for Turkey to mediate, has expressed hope the talks can lead to a ceasefire agreement.

March 11

Mr Zelenskyy's office announces that emergency services personnel have been stationed in the Ukrainian city of Dnipro after news of explosions on Friday morning. Three Russian air strikes hit the city close to the a kindergarten and an apartment building. One person is killed.

US President Joe Biden will call for an end to normal trade relations with Russia over its invasion of Ukraine, clearing the way for increased tariffs on Russian imports.

The move comes after the US Senate on Thursday voted to approve legislation providing $1.5 trillion to keep the federal government operating beyond this week and $13.6 billion to help Ukraine.

On the ground, food is running short in the besieged southern Ukrainian city of Mariupol, the local Red Cross has warned.

“No electricity, water and gas supply, meaning no means for heating,” said Sasha Volkov, deputy head of the Red Cross delegation in the city. “Some people still have food but I am not sure for how long it will last.”

March 12

Air raid sirens sound in several Ukrainian cities as Russian forces move closer to the capital, Kyiv.

Russian forces are slowly surrounding Kyiv, with Ukrainian presidential adviser Mykhailo Podolyak calling it a “city under siege”. He tweets that it is “ready to fight”, with checkpoints prepared and supply lines in place.

“Kyiv will stand until the end,” he says.

March 13

Russian forces launch a missile attack on a Ukrainian military installation near the Polish border on Sunday, the westernmost attack of the conflict so far. About 30 rockets are fired at the site, with figures so far suggesting a death toll of 35.

Mr Zelenskyy calls it a “black day” and again urges Nato leaders to establish a no-fly zone over the country, a plea that the West has said could escalate the war to a nuclear confrontation.

Tens of thousands of people rally in cities across Europe on Sunday to protest against Moscow’s war in Ukraine, with small vigils taking place in Russia despite a crackdown by authorities.

March 14

Mr Zelenskyy will address both chambers of the US Congress via video on Wednesday as his nation continues to fend off invading Russian forces, Democrat leaders say.

The EU approves a new set of sanctions on Russia linked to its invasion of Ukraine. Senior US and Chinese officials hold a long meeting in Rome, with the US expressing “deep concerns” during “intense” discussions on Russia's war in Ukraine and other security matters.

Besieged Ukrainians hold out hope on Monday that renewed diplomatic talks with Russia might open the way for more civilians to flee, a day after Moscow escalated its offensive by shelling areas perilously close to the Polish border.

Ukraine’s leader issues a warning that the attacks could expand to neighbouring countries.

Another residential building in the Podilsk area also comes under attack.

Mr Zelenskyy says Ukraine should accept that it will not join Nato and that Kyiv is prepared to have security guarantees instead of joining the military alliance.

March 19

Mr Zelenskyy says that Russia is blocking humanitarian aid to besieged cities including Mariupol, where hundreds of people are trapped beneath rubble in a bombed-out theatre. The port city, which had a prewar population of nearly half a million, is rapidly becoming the epicentre of human suffering in the conflict. Russia later claims to have used a Kinzhal hypersonic missile to attack an arms depot in western Ukraine, the first use of the device that Mr Putin claims can travel at 10 times the speed of sound.

March 20

Russia's call for Ukrainian forces now trapped in Mariupol to surrender is rejected by Mr Zelenskyy. “There can be no question of any surrender, laying down of arms,” he said. Ukraine says more than 7,000 people were moved out the city overnight. Analysts said Russia's advances are still stalled across most of Ukraine, except around Mariupol.

Russia confirms that Anrei Paly, deputy commander of the Black Sea Fleet for military-political affairs, was killed at Mariupol.

March 22

Mr Zelenskyy said Russian forces not only blocked a humanitarian convoy trying to reach besieged Mariupol with desperately needed supplies, but took captive some of the rescue workers and bus drivers. He said the Russians had agreed to the route.

“We are trying to organise stable humanitarian corridors for Mariupol residents, but almost all of our attempts, unfortunately, are foiled by the Russian occupiers, by shelling, or deliberate terror,” Mr Zelenskyy said.

March 23

A total of 4,554 people were evacuated from Ukrainian cities through humanitarian corridors, a senior official said, considerably fewer than managed to escape the previous day.

“We will not give anything away. We will fight for every metre of our territory,” the Ukrainian president said.

March 31

Heavy fighting raged on the outskirts of Kyiv and other zones amid indications the Kremlin was using talk of de-escalation as a cover while regrouping and resupplying its forces in preparation for a stepped-up offensive in eastern Ukraine.

Senior Ukrainian figures said Russian troops were likely to retreat to southern and eastern strongholds in Ukraine after partially withdrawing from around Kyiv.

They rejected suggestions that the war would develop into a drawn-out conflict like the one in Afghanistan, after President Volodymyr Zelenskyy suggested some western countries were quietly hoping Russia would remain bogged down.

Russia’s announcement that it was scaling back its operations around Kyiv was met with scepticism by western leaders, amid uncertainty over whether troops were really withdrawing or merely regrouping.

April 3

President Volodymyr Zelenskyy accused Russia of killing civilians in Bucha, outside Kyiv, where bodies were found on streets after the town was retaken by Ukrainian forces.

Meanwhile, Former German chancellor Angela Merkel defended her 2008 decision to block Ukraine from immediately joining Nato.

April 5

The US, in co-ordination with the G7 and EU, will ban “all” new investments in Russia on Wednesday in its latest round of sanctions.
