U.S. President Donald Trump has made clear that he wants a deal to end Russia’s war in Ukraine by August 8, the United States told the United Nations Security Council on Thursday.

Trump in July set a 50-day deadline for the agreement with Ukraine, threatening tariffs if a deal was not made. On Monday, during his meeting with U.K. Prime Minister Keir Starmer, he said he was shortening this deadline to “10 or 12 days.”
