An Afghan official said a suicide attacker wearing a police uniform blew himself up at a U.S. base in eastern Afghanistan, wounding five Americans, according to AP. The spokesman for Paktia province, Roullah Samoun, says the attack occurred Thursday night in the Dand aw Patan district near the Pakistan border about 35 miles (70 kilometers) east of Gardez. A U.S. spokesman, Lt. Col. Todd Vician, says U.S. officials have a report that some Americans were wounded, but he had no further details. The reported attack occurred about 400 miles (640 kilometers) northeast of a Taliban town under siege by U.S. and Afghan troops in Helmand province.
