"We've just become the first nation to pass a law involving a total ban of all ships with any Russian connection whatsoever from entering British ports," Transport Secretary Grant Shapps said on Twitter.
Ukraine's Foreign Minister Dmytro Kuleba called on Tuesday for more international sanctions against Russia after what he said was a "barbaric" attack on the city of Kharkiv.
"Barbaric Russian missile strikes on the central Freedom Square and residential districts of Kharkiv. (Russian President Vladimir) Putin is unable to break Ukraine down. He commits more war crimes out of fury, murders innocent civilians," Kuleba said on social media.
Ukraine's President Volodymyr Zelensky officially applied on Monday to join the European Union, with the application being on its way to Brussels for processing, Ukrainian President's Office deputy head Andrij Sybiha wrote on Facebook.
In response, the heads of state for eight different EU member states – Bulgaria, Estonia, Lithuania, Latvia, Poland, Slovakia, Slovenia and the Czech Republic – pushed for vastly expediting Ukraine's admission into the bloc.
"We call on EU member states to consolidate highest political support to Ukraine and enable the EU institutions to conduct steps to immediately grant Ukraine an EU candidate country status and open the process of negotiations," the leaders wrote, as noted on the official website of the Lithuanian president.
This follows Slovakian Prime Minister Eduard Heger telling Politico that Ukraine should have a "special track" towards EU membership.
“They fight for themselves, they fight for us — they fight for freedom,” Heger said told Politico. “We have to realize that they are protecting our system, our values and we have to be together with them. So there is no time to hesitate on this.”
Overall, support for Ukraine is strong in the EU, as noted in a recent op-ed in The Jerusalem Post by EU High Representative for Foreign Affairs and Security Policy Josep Borrell.
"This is a matter of life and death," Borrell noted. "I am preparing an emergency package to support the Ukrainian armed forces in their fight."
European Commission President Ursula von der Leye told Euronews Sunday that Ukraine is "one of us and we want them in the European Union."
Several European nations have already sent considerable funds and munitions towards Ukraine, as well as levying sanctions against Moscow, as have their allies abroad such as the US.
As the war enters its sixth day, around 350,000 people have entered Poland from Ukraine since Russia invaded the country, a Polish deputy interior minister said on Tuesday.
"Over the last 24 hours 100,000 people crossed the Polish-Ukrainian border," Maciej Wasik told public broadcaster Polskie Radio 1. "In total, since Thursday, there have already been 350,000 refugees."
Ukrainian Foreign Minister Dmytro Kuleba said on Tuesday morning that US Secretary of State Antony Blinken had offered his country more support in the form of sanctions and weapons.
"In our call, Secretary Blinken affirmed that the US support for Ukraine remains unfaltering," Kuleba said on Twitter. "I underscored that Ukraine craves for peace, but as long as we are under Russia's assault we need more sanctions and weapons. The US Secretary of State assured me of both. We coordinated further steps."
The prospects of a diplomatic resolution to the Ukraine crisis are slim at the moment, Britain's Deputy Prime Minister Dominic Raab said on Tuesday.
Asked on LBC Radio whether Russian billionaire businessman Roman Abramovich, who has accepted a Ukrainian request to help negotiate an end to the Russian invasion of Ukraine, could be key to the solution, Raab responded: "Who knows?"
