An American service member has been killed in an insurgent attack in eastern Afghanistan, the U.S. military said. Sunday's attack in the town of Bargh-e-Matal in Nuristan province also wounded some other troops, said Lt. Cmdr. Christine Sidenstricker. She did not have an exact number of wounded. The death brings to 105 the number of U.S. troops killed in Afghanistan so far this year, compared with 151 U.S. deaths in all of 2008. Overall, 194 international troops have died in Afghanistan this year, according to an Associated Press count based on official announcements. Elsewhere in the east, a roadside bomb killed a district police chief and his three bodyguards Monday in Wardak province, said Shahidullah Shahid, a spokesman for the governor.
