European leaders urged US President Donald Trump on Wednesday not to strike a unilateral Ukraine peace deal with his Russian counterpart Vladimir Putin during their one-on-one meeting later this week in Alaska.

BRUSSELS (AP) — European leaders have praised President Donald Trump for agreeing to allow U.S. military support for a force they are mustering to police any future peace in Ukraine — a move that vastly improves the chances of success for an operation that could prove essential for the country’s security.

But U.S. president “as always, talked a lot about what he would do, but in a way that no one could say what exactly he was going to do,” official tells POLITICO.
