US President Trump gives Moscow 50-day ultimatum over Ukraine war

US President Donald Trump told Russia on Monday to end its war in Ukraine within 50 days or face massive new economic sanctions, as he laid out plans for infusions of weaponry for Kyiv via NATO. "We're going to be doing very severe tariffs if we don't have a deal in 50 days, tariffs at about 100 percent," Trump said during an Oval Office meeting with NATO Secretary General Mark Rutte.
