Russian President Vladimir Putin has proposed Moscow as the venue for a potential summit with Ukrainian leader Volodymyr Zelenskyy, according to sources close to the talks.

"Putin mentioned Moscow" during their call on Monday, one of the sources told AFP, adding that Zelensky had said "no" in response.

A diplomatic source close to the discussions said that European leaders had told Trump that Putin's proposal "did not seem like a good idea."

Putin's suggestion comes a day after Zelenskyy held talks with U.S. President Donald Trump and European leaders in Washington.

Zelenskyy confirmed to reporters outside the White House he was "ready" for a bilateral with bitter foe Putin, whose invasion of Ukraine has led to tens of thousands of deaths.
