British Prime Minister Keir Starmer says his country will host an international meeting of military officials on Thursday to move forward with "practical plans" to support Ukraine's future security.



Starmer presided over video conference of leaders from nearly 30 countries. It brought together Ukrainian President Volodymyr Zelenskyy, leaders of EU countries and other European nations, as well as Canada, Australia and NATO.



Starmer issued a statement referring to what he called "the Kremlin's dithering and delay" over a 30-day ceasefire proposal presented by US President Donald Trump's administration.



Starmer told reporters that the meeting participants agreed to continue pressuring Russia, keep military aid flowing to Ukraine, and to further tighten restrictions on Russia's economy.



He said the efforts are meant to weaken "Putin's war machine", and bring him to the negotiating table.



The prime minister also commented on a campaign led by Britain and France to form a "coalition of the willing" that will deploy peacekeepers to Ukraine after a ceasefire is implemented. He said "new commitments were put on the table."



The proposed deployment is predicated on security guarantees from the US. But it remains to be seen how much cooperation Washington is willing to provide. Russia is strongly opposing the plan.



The online conference comes after Starmer convened an in-person meeting of more than a dozen world leaders, including Zelenskyy, in London on March 2.
