Six Afghan soldiers were killed, one of them beheaded, in a battle with Taliban insurgents, authorities said Tuesday, also reporting at least 10 militants had died in fighting. Five of the soldiers were killed in a gunfight that erupted after Taliban militants ambushed an army patrol late Monday in the Bala Buluk district of Farah province, military corps commander for western Afghanistan Fazal Ahmad Sayar said. "Five soldiers were killed and five were wounded. The militants beheaded one of the wounded soldiers," he said.
