Trump threatens tougher sanctions after Russia’s heaviest strikes on Ukraine

Donald Trump has threatened tougher sanctions against Russia after its heaviest aerial bombardment on Ukraine since the war began.

Sunday’s strikes killed four people, including a mother and her baby, and damaged Ukraine’s main government building in Kyiv for the first time.

The attack – which Ukraine said involved at least 810 drones and 13 missiles – has led to growing calls for stronger Western action against President Vladimir Putin.

Speaking to reporters after the bombardment, the US president said he was “not happy with the whole situation.”

Trump has previously threatened harsher measures against Russia, but not taken any action when Putin ignored his deadlines and threats of sanctions.

Asked on on Sunday if he was prepared to move to the “second phase” of punishing Moscow, Trump replied: “Yeah, I am,” though gave no details.

The threat follows remarks from US Treasury Secretary Scott Bessent, who said Washington was prepared to escalate economic pressure but needed stronger European backing.

In an interview with NBC, Bessent said that, if EU nations increased sanctions and secondary tariffs on countries which buy Russian oil, “the Russian economy will be in total collapse, and that will bring President Putin to the table”.

He added: “We are in a race now between how long can the Ukrainian military hold up, versus how long can the Russian economy hold up.”
