Afghan soldier opens fire on U.S. troops

Three American service members were wounded Sunday afternoon when an Afghan soldier opened fire on them at a base in the country’s southern Helmand province, U.S. officials said. Capt. William Salvin, a U.S. military spokesman in Afghanistan, said security forces on base killed the attacker to end the assault. “The U.S. soldiers are receiving medical treatment at this time, and we will release more information when available,” he said.
