U.S. President Donald Trump indicated on Wednesday he will consider providing more of the Patriot missiles that Ukraine needs to defend against mounting Russian strikes, adding that Russian President Vladimir Putin "really has to end that war."

His remarks came after a 50-minute meeting with Ukrainian President Volodymyr Zelenskyy on the sidelines of a NATO summit in The Hague. Both leaders described it as a positive step in a conflict that Trump described as "more difficult than other wars."

During a news conference in which he celebrated his own diplomatic efforts in the Middle East, Trump said the Patriots were "very hard to get" but that "we are going to see if we can make some of them available."
