US President Donald Trump on Wednesday warned his Russian counterpart, Vladimir Putin, of “devastating” sanctions if Russia refused a deal on a ceasefire in the Ukraine war.

Speaking after a meeting with the Ireland Prime Minister, Micheal Martin, at the White House, Trump said that US negotiators are headed to Russia “right now” for talks on a possible ceasefire with Ukraine, a day after Kyiv agreed to a 30-day truce. He, however, did not give details. The White House later said that his special envoy, Steve Witkoff, was going to Moscow later this week.

“We could do things very bad for Russia. It would be devastating for Russia. But I don’t want to do that because I want to see peace, and we’re getting close to maybe getting something done,” Trump told reporters.

“People are going to Russia right now as we speak. And hopefully, we can get a ceasefire from Russia. And if we do, I think that would be 80 percent of the way to getting this horrible bloodbath finished,” he said while speaking about the three-year war.
