Donald Trump will speak to Vladimir Putin by phone later today - with the White House saying "we've never been closer to a peace deal" in Ukraine.
In a post on Truth Social, the US president said he would be speaking to his Russian counterpart on Tuesday morning - adding: "Many elements of a Final Agreement have been agreed to, but much remains.
"Thousands of young soldiers, and others, are being killed. Each week brings 2,500 soldier deaths, from both sides, and it must end NOW."
While aboard Air Force One, Mr Trump had told reporters that land and power plants were part of the conversation on bringing the war to a close.
After crunch talks in Saudi Arabia between US and Ukrainian diplomats, Volodymyr Zelenskyy said last week that Kyiv would accept a 30-day pause in fighting if Russia committed to it as well.
Since then, Mr Putin has said he agrees fighting in Ukraine should end - but warned "lots of questions" remain over the proposed ceasefire.
He has also met US envoy Steve Witkoff to discuss the details of the proposal.
It comes as Ukraine's air defence units said they shot down 90 of 174 drones launched by Russia in an overnight attack on Monday.
Russia has been attacking the Odesa region with drones and missiles on a daily basis for three weeks, the air force said - adding that 70 other drones were disrupted in the attack.
Odesa Governor Oleh Kiper added a civilian was injured during the strikes, which damaged a kindergarten, a house, a shop and a car.
Biden children's security detail revoked
In other developments, Mr Trump said on Truth Social that he is "immediately" revoking Secret Service protection that was being given to Joe Biden's children.
He claimed 18 agents were assigned to Hunter Biden's protective detail while in South Africa this week - and added Ashley Biden had 13 agents assigned to her detail who "will be taken off the list".
