An Afghan official says Taliban terrorists have ambushed a group of Afghan police while they ate lunch and killed 20 officers. Daud Ahmadi, the spokesman for Helmand province's governor, says terrorists also killed the mother of one of the policemen after she pleaded with the insurgents to spare her son's life. The Wednesday attack came in a remote area of Helmand. A Taliban spokesman, Qari Yousef Ahmadi, says two Taliban were killed and four wounded during the ambush. Ahmadi says 32 police were killed, but that number has not been confirmed by Afghan officials. Ahmadi says the slain police were assigned as bodyguards for the district chief of Musa Qala, a region filled with Taliban fighters.
