"Your visit to Kyiv at this difficult time for Ukraine is a strong sign of support. We really appreciate it," Mr <a href="https://www.thenationalnews.com/world/us-news/2022/03/14/volodymyr-zelenskyy-to-address-full-us-congress/" target="_blank">Zelenskyy</a> said in an online post. Brief footage released by his office showed him speaking in Ukrainian and English to Polish Prime Minister Mateusz Morawiecki, the Czech Republic's Petr Fiala and Slovenia's Janez Jansa, who were also due to meet Ukrainian officials. Also in attendance was Polish Deputy Prime Minister Jaroslaw Kaczynski, leader of the country's ruling PiS party, who is regarded as the main decision-maker in the country. Russian air strikes and shelling hit <a href="https://www.thenationalnews.com/world/uk-news/2022/03/15/battlefield-medical-supplies-critically-low-in-kyiv-warns-volunteer/" target="_blank">Kyiv</a> on Tuesday, killing at least four people, authorities said, as invading forces tightened their grip and the mayor announced a 35-hour curfew. "It is here, in war-torn Kyiv, that history is being made. It is here, that freedom fights against the world of tyranny. It is here that the future of us all hangs in the balance," Mr Morawiecki wrote on Twitter. The Czech Republic and Poland, former communist members of the EU and Nato, have been among the strongest backers of Ukraine in Europe since the Russian invasion. Ukrainian Prime Minister Denys Shmyhal hailed what he said was the "courage of true friends" and said the leaders would discuss support for Ukraine and further sanctions. Polish state-run broadcaster TVP Info reported that Mr Morawiecki and Mr Kaczynski also went to meet the Kyiv authorities. Mr Fiala said the decision to visit was made in consultation with European Council President Charles Michel and European Commission President Ursula von der Leyen. The idea of the trip was agreed to at an <a href="https://www.thenationalnews.com/world/europe/2022/03/11/eu-unveils-fourth-set-of-sanctions-against-russia/" target="_blank">EU leaders' summit in Versailles in France last week</a>, top Polish official Michal Dworczyk said. But an EU official said there was no "formal mandate" extended by Brussels. "It's a very valid initiative. Every initiative to bring peace back to Ukraine is, of course, welcome," the official said. "Some leaders might also wonder: will this jeopardise or will this improve conditions for negotiations with the Russians? It remains to be seen, of course. It's a fine line." Russia calls its actions a "special military operation" to "de-Nazify" Ukraine, which Kyiv and its western allies reject as a pretext for an unjustified and illegal attack.
