Members of Turkish-backed Free Syrian Army, a militant group active in parts of northwest Syria, load their goods after shopping from a market to their vehicle in Akcakale, Turkey. The military action is part of a campaign to extend Turkish control of more of northern Syria, a large swath of which is currently held by Syrian Kurds, whom Turkey regards as a threat. U.S. President Donald Trump granted tacit American approval to this campaign, withdrawing his country's troops from several Syrian outposts near the Turkish border. Getty Images
