Israel staged an unprecedented air strike on Qatar on Tuesday, targeting Hamas leaders at their homes in Doha.
Here is what we know so far.
How did Israel's attack happen?
News of explosions in Qatar broke early on Tuesday evening. Witnesses reported several blasts and smoke was seen rising above Doha.
Shortly afterwards, the Israeli air force announced it had carried out a "precise strike" against Hamas leadership. Israeli outlet Channel 12 reported that about 10 jets took part in the strike.
Prime Minister Benjamin Netanyahu said it was a "wholly independent Israeli operation", although a White House official said the US was informed in advance.
US President Donald Trump later said he was “very unhappy” about the strike. “I’m not thrilled about the whole situation,” he told reporters.
"This was a decision made by Prime Minister Netanyahu, it was not a decision made by me," Mr Trump said in a post on Truth Social.
It is the second time in three months that Qatar has come under military attack, after Iran launched missiles at a US-operated airbase in June.
Where did the attack happen?
Qatar said the attack hit "residential buildings housing several members of the political bureau of Hamas".
Smoke was seen rising over the Katara District in Doha. Qatar said the situation was secure as it confirmed the sounds heard were due to the Israeli attack.
It said authorities were taking necessary measures to contain repercussions and ensure the safety of residents.
Who was targeted?
Israel said it had targeted Hamas’s leadership, but the group said its senior leaders had survived.
It said the attack killed five people - the son of senior leader Khalil Al Hayya, the director of his office, and three others. According to a senior Hamas official, the attack “hit the office" of Mr Al Hayya, Hamas’s top negotiator. Qatar said a sixth person, a member of its security forces, was killed "while performing his duties" at the site of the attack, and others injured.
After the killings of key figures Ismail Haniyeh and Yahya Sinwar last year, Hamas has been run by a six-man leadership that brought together officials in the occupied Palestinian territories and the diaspora.
Mr Al Hayya had been leading the group’s negotiating team in efforts to end the war in Gaza. Talks have taken place in Doha as Qatar acts as a go-between, along with Egypt.
Also in Hamas's collective leadership are two operational field commanders and Muhammad Darwish, the head of the group's Shura Council, who lives in Turkey.
How have the countries involved reacted?
Qatar condemned what it called a cowardly attack on its territory. Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani called it “state terrorism”.
Speaking to journalists late on Tuesday, he called the strike "100 per cent treacherous” and refuted suggestions that Doha had been warned before the attack. Sheikh Mohammed said US officials first informed Qatar of the strike 10 minutes after it began.
"There is a rogue actor practising ongoing political chaos in this region and violating the sovereignty of states there," the Prime Minister said of Israel.
Majid Al Ansari, spokesman for the Qatari Foreign Ministry, added: "This criminal assault constitutes a blatant violation of all international laws and norms, and poses a serious threat to the security and safety of Qataris and residents in Qatar."
The Israeli army said it used "precise munitions" to mitigate harm to civilians.
"For years, these members of the Hamas leadership have led the terrorist organisation's operations, are directly responsible for the brutal October 7 massacre, and have been orchestrating and managing the war against the state of Israel," it said.
Middle East leaders, including those from Lebanon, Egypt, Saudi Arabia, Syria and the UAE, condemned the attack.
The UK warned against "further escalation in violence", a US senator called the Doha strike "unfortunate" and Pope Leo called the situation "very serious".
What did Israel say?
Israeli Prime Minister Benjamin Netanyahu said the strike on Qatar “can open a door for the end of the war in Gaza”.
Speaking at an event hosted by the US Embassy in Jerusalem, he said Hamas leaders "were meeting in exactly the same place where they celebrated this savagery almost two years ago", referring to the October 7 attacks.
He said if Mr Trump’s ceasefire proposals are accepted by Hamas, the war could end “immediately”.
