Donald Trump has said he is “thinking” of going to Turkey on Thursday for potential peace talks between Ukraine and Russia’s leaders.
The US president, who previously claimed he could end the conflict in a day, has pushed for both sides to meet to bring the fighting to an end.
On Sunday, Ukraine’s Volodymyr Zelenskyy called out Vladimir Putin to meet him on Thursday in Istanbul, but the Kremlin leader has yet to respond.
Speaking late on Monday, Mr Trump said: “I was thinking about flying over. I don’t know where I am going be on Thursday.
“I’ve got so many meetings.
“There’s a possibility there I guess, if I think things can happen.”
Mr Trump has headed to the Middle East this week on the first major foreign trip of his second administration, visiting Saudi Arabia, Qatar and the UAE.
Mr Zelenskyy backed the prospect of Mr Trump attending the talks.
He said: “I supported President Trump with the idea of direct talks with Putin. I have openly expressed my readiness to meet.
“And of course, all of us in Ukraine would appreciate it if President Trump could be there with us at this meeting in Turkey.”

Russia playing for time?
However, Kremlin spokesperson Dmitry Peskov, speaking on Monday, refused to say who, if anyone, would be travelling to Turkey from the Russian side.
“Overall, we’re determined to seriously look for ways to achieve a long-term peaceful settlement. That is all,” Mr Peskov said.
This came after the “coalition of the willing”, including Sir Keir Starmer, threatened Russia with fresh sanctions if it failed to comply with an unconditional 30-day ceasefire starting on Monday.

Russia effectively rejected this proposal, instead calling for direct negotiations in Istanbul with Ukraine, at which Mr Zelenskyy challenged Mr Putin to make the trip himself.
Despite Russia’s claims towards wanting peace, Ukraine’s allies remained deeply sceptical about prospects for talks and whether Mr Putin was serious.

European Union commission vice president Kaja Kallas said: “We want to see that Russia also wants peace.
“It takes two to want peace, it takes only one to want war, and we see that Russia clearly wants war.”
Meanwhile, Russia continued its nightly attacks on Ukraine.
Overnight into Tuesday, Ukraine said Moscow launched more than 100 drones.
