The Sangin district of Helmand province, one of Afghanistan's most deadly, has claimed the lives of three more American servicemen. An Afghan police commander and his men invited three special forces members to dinner, saying they planned to discuss security. "During dinner, the police commander and his colleagues shot them and then fled," a senior Afghan official told Reuters. Three were killed. "It looks like he had drawn up a plan to kill them previously," he added. Shootings like these have grown distressingly common, and have alienated U.S. troops from their potential local allies. Since January, 28 people have been killed in similar attacks.
