Ukrainian President Volodymyr Zelensky met Thursday in London with UK Prime Minister Keir Starmer in a strong show of support on the eve of a key US-Russia summit from which Kyiv and its European allies have been excluded.

European and NATO leaders announced Sunday they will join President Volodymyr Zelenskyy in Washington to present a united front in talks with President Donald Trump on ending Russia’s war in Ukraine and firming up U.

Zelenskyy said at a news briefing in Kyiv that Putin wants the remaining 9,000 square kilometers (3,500 square miles) of Donetsk under Kyiv’s control, where the war’s toughest battles are grinding on, as part of a ceasefire plan. He said the Russian position was conveyed to him by U.S. officials.

Russia has said its demands from negotiations with Ukraine, which include Kyiv's troops pulling out of several regions in the east, haven't changed.

European and NATO leaders will join Zelensky in Washington for talks with President Trump on ending Russia’s war in Ukraine. Russia agrees to allow NATO-like security protections for Ukraine, U.S. envoy says.

The U.S. president declared Saturday that he would forego his previous demand for an initial ceasefire, making it easier for Putin to continue the war and dictate terms of a peace agreement at gunpoint.
