The United States has pulled out of peace negotiations between Ukraine and Russia after Vladimir Putin declined to sign up to a ceasefire.

The State Department confirmed it will no longer “fly around the world at the drop of a hat” for meetings.

It comes after Moscow accused Kyiv of attacking a busy market in Russian-controlled southern Ukraine in a drone strike it said had killed at least seven civilians and wounded more than 20.

Meanwhile, Kyiv said the attack had killed only military personnel.

State Department spokeswoman Tammy Bruce said: "The nature of how this would change is we would not – we certainly are still committed to it and will help and do what we can.

"But we are not going to fly around the world at the drop of a hat to mediate meetings, that it is now between the two parties."

It comes as President Trump has reportedly become increasingly frustrated with Vladimir Putin, and the Kremlin's refusal to budge over a potential ceasefire deal.

Sources close to the Trump administration told Bloomberg that White House officials have prepared a set of options to increase economic pressure on Russia, however they did not disclose what these were.

Kyiv and its allies have been urging the US to step-up pressure on Moscow, including through expanding sanctions on its energy exports and oil revenues, to force Putin to the negotiation table.
