Three policemen and two Afghan army officers were also killed in the attack, said a senior police official. The attack took place as a deadline expired for U.S. special forces to quit the eastern province of Wardak, after Afghan President Hamid Karzai accused them and Afghans working for them of overseeing torture and killings in the area. An Afghan interior ministry official said the attack occurred in Jalriz district of Wardak. U.S. Secretary of Defense Chuck Hagel, who left Afghanistan early on Monday after a three-day visit, raised the sensitive issue of Wardak when he met Karzai. U.S. forces have denied involvement in any abuses in Wardak. Hagel wanted a deal on their continued deployment, but acknowledged no breakthroughs were made in his talks with Karzai.
