Russia on Monday accused Ukraine of trying to attack President Vladimir Putin’s residence in northern Russia, which President Trump said he was “very angry” about, even as Kyiv has denied it happened.

The Kremlin’s Foreign Minister Sergei Lavrov said Moscow’s negotiating position to end its war in Ukraine was under review after it claimed Kyiv tried to attack the presidential residence in the Novgorod region overnight with 91 long-range drones. Lavrov said all drones were destroyed by Russian air defenses, with no injuries or damage.

Ukrainian President Volodymyr Zelensky, meanwhile, said Russia’s claims were “a complete fabrication intended to justify additional attacks against Ukraine” and undermine peace talks, according to a post to the social platform X.

But Trump later on Monday appeared to take Russia’s side.

“I don’t like it, it’s not good. I heard about it this morning. You know who told me about it? President Putin told me about it. Early in the morning he said he was attacked. That’s no good, it’s no good,” Trump told reporters at his Mar-a-Lago estate in Palm Beach, Fla., of the claimed strike.

“It’s a delicate period of time. This is not the right time,” Trump added, likely referring to ongoing peace negotiations between Russia and Ukraine. “It’s one thing to be offensive, because [Russia is] offensive, it’s another thing to attack [Putin’s] house. It’s not the right time to do any of that. … I was very angry about it.”

Asked if there’s evidence of the attack, Trump replied: “Well, we’ll find out. You’re saying maybe the attack didn’t take place? That’s possible, I guess, but President Putin told me this morning.”

White House press secretary Karoline Leavitt confirmed Trump’s call with Putin, saying in a post on X that the president had “concluded a positive call with President Putin concerning Ukraine.”

Rep. Don Bacon (R-Neb.) later criticized Trump for appearing to side with Russia, accusing Putin of frequently lying.

“President Trump and his team should get the facts first before assuming blame. Putin is a well known boldface liar,” Bacon wrote on X.

Russia has already promised to retaliate against Ukraine and said targets had already been selected for such strikes.

“Such reckless actions will not go unanswered. The targets for retaliatory strikes and the timing of their implementation by the Russian armed forces have been determined,” Lavrov said.

Zelensky in his post warned that Russia would use the alleged attack to justify strikes against Ukraine, including government buildings in Kyiv.

“Russia is at it again, using dangerous statements to undermine all achievements of our shared diplomatic efforts with President Trump’s team. We keep working together to bring peace closer,” he wrote.
