President Donald Trump on Monday said he will reduce a 50-day ceasefire ultimatum for Russia "to a lesser number" because he's disappointed in President Vladimir Putin over continued strikes against Ukraine.

Trump spoke briefly with reporters while welcoming British Prime Minister Keir Starmer and Starmer's wife, Victoria, at Trump Turnberry golf club in Turnberry, Scotland.

"I've spoken to President Putin a lot. I always got along with him very well. But five times and every time ... four times maybe ... but we've had discussions," Trump said before turning to Starmer. "You and I have had discussions we thought we had that settled numerous times. And then President Putin goes out and starts launching rockets into some city like Kyiv, and kills a lot of people in a nursing home or whatever. You have bodies lying all over the street. And I say, that's not the way to do it.

"So we'll see what happens with that. I'm very disappointed. I'm disappointed in President Putin, very disappointed in him. So we're going to have to look and I'm going to reduce that 50 days that I gave him to a lesser number, because I think I already know the answer."

Russian spokesperson Dmitry Peskov said Monday there were no plans for a possible meeting between Putin and Trump in Turkey, according to Tass.

Peskov's comment followed Turkish President Tayyip Erdogan on Friday saying he may speak to his Russian and U.S. counterparts this week to see if a leaders meeting in Istanbul is possible to discuss the war in Ukraine, after Russian and Ukrainian delegations met there last week.
