The talks took place in the warring capitals of Moscow and Kyiv, from Washington and Riyadh, Saudi Arabia, to countries across Europe

Russia will announce who is attending proposed peace talks in Turkey on ending the war in Ukraine when President Vladimir Putin sees fit to, the Kremlin said on Tuesday, declining to say at this stage whether or not Putin will attend himself.

Trump had previously left open the possibility of attending the talks himself, despite the logistical challenges his visit would present.
