Trump calls Putin 'crazy' after deadly strikes on Ukraine, warns of downfall of Russia

US President Donald Trump called Russian President Vladimir Putin "crazy" on Sunday after Moscow targeted Ukraine with a deadly series of attacks that killed at least 13 people amid a massive prisoner exchange.

"I've always said that he wants ALL of Ukraine, not just a piece of it, and maybe that's proving to be right, but if he does, it will lead to the downfall of Russia!" Trump said in a post on his Truth Social platform.

"I've always had a very good relationship with Vladimir Putin of Russia, but something has happened to him. He has gone absolutely CRAZY!" he added.

The remarks coming from Trump against Putin signal an increasing frustration with Moscow.

He said Putin is "needlessly killing a lot of people" by firing missiles and drones into Ukrainian cities "for no reason whatsoever."

Trump considering additional sanctions on Moscow

Donald Trump told the media he was "not happy with what Putin is doing," and replied "absolutely" when asked if he was considering further sanctions on Russia. 

His comments come after Russian launched the biggest aerial strike targeting Ukraine since its full-scale invasion in 2022.

"I've known him a long time, always gotten along with him, but he's sending rockets into cities and killing people and I don't like it at all," he said.

"We're in the middle of talking and he's shooting rockets into Kyiv and other cities. I don't like it at all. And I'm surprised. I'm very surprised."
