Talks between the U.S., Ukraine and European officials to discuss ending Russia's war in Ukraine faltered as Secretary of State Marco Rubio abruptly cancelled his trip to London.

Zelenskyy on Tuesday ruled out ceding territory to Russia in any deal before talks set for Wednesday in London among U.S., European and Ukrainian officials. “There is nothing to talk about. It is our land, the land of the Ukrainian people,” Zelenskyy said.

Diplomats from the UK, France, Germany, Ukraine and the US will hold fresh talks in London on Wednesday aimed at securing a ceasefire in the three-year war between Ukraine and Russia. The talks come amid growing speculation that Russia might be willing to halt its invasion along current front lines in return for significant concessions.
