WASHINGTON -- US President Donald Trump on Friday set Nov 27 as the deadline for accepting a 28-point peace plan proposed by his administration to end the Russia-Ukraine conflict.

"I've had a lot of deadlines, but if things are working well, you tend to extend the deadlines," Trump told Fox News Radio. "But Thursday is it -- we think an appropriate time."

Ukraine was losing land and "will lose in a short period of time," he said.

Ukrainian President Volodymyr Zelensky said Friday on X, following a phone call with US Vice President JD Vance, that the Ukrainian side "agreed to work together with the US and Europe at the level of national security advisors to make the path to peace truly doable."

In an address to the nation, Zelensky said: "Ukraine could now face a very difficult choice: either the loss of dignity, or the risk of losing a key partner. Either the difficult 28 points, or an extremely difficult winter."
