LONDON, May 15: UK premier Keir Starmer said the "ball was in Russia's court" and that President Vladimir Putin would "sooner or later" have to "come to the table," after a virtual summit on Saturday to drum up support for a coalition willing to protect any eventual ceasefire in Ukraine.
The British prime minister told some 26 fellow leaders as they joined the group call hosted by Downing Street that they should focus on how to strengthen Ukraine, protect any ceasefire and keep up the pressure on Moscow.
While Ukraine had shown it was the "party of peace" by agreeing to a 30-day unconditional ceasefire, "Putin is the one trying to delay," he said.
"If Putin is serious about peace, I think it's very simple, he has to stop his barbaric attacks on Ukraine and agree to a ceasefire, and the world is watching," he added.
Military chiefs will now meet again on Thursday in the UK as the coalition moves into "the operational phase," Starmer said after the talks.
"The group that met this morning is a bigger group than we had two weeks ago, there is a stronger collective resolve and new commitments were put on the table this morning," he added.
EU chief European Commission President Ursula von der Leyen said in a message on X that Russia has to show "it is willing to support a ceasefire leading to a just and lasting peace".
And Dutch Prime Minister Dick Schoof also said on X it was "now important to continue to exert pressure on Russia to come to the negotiating table."
Overnight fighting continued in the relentless three-year war, with Russia saying it had taken two more villages in its Kursk border region where it has launched an offensive to wrest back seized territory.
- Fighting in Kursk region -
As moves have gathered pace for a ceasefire, Moscow has pushed this week to retake a large part of the land that Ukraine originally captured in western Kursk.
But Ukrainian leader Volodymyr Zelensky, who joined the talks, denied Saturday any "encirclement" of his troops in the Kursk region.
"Our troops continue to hold back Russian and North Korean groupings in the Kursk region," he said on social media.
The Russian defence ministry said troops took control over the villages of Zaoleshenka and Rubanshchina -- north and west of the town of Sudzha, the main town that Moscow reclaimed this week. �"AFP
