At least two suicide bombers stormed a police headquarters in southeastern Afghanistan on Saturday, killing 12, officials said.
Several others were injured when the bombers attacked the main police headquarters in Sharana, the capital city for Paktika province, governor Muhebullah Samim said.
"Two bombers disguised in police uniforms attacked the police headquarters," Samim said.
Abdullah Shah, the deputy provincial police chief, said three bombers equipped with explosive-filled vests and automatic weapons attacked the main station.
"Twelve of our brave police forces were martyred in these attacks and several others were injured," he said.
Taliban spokesman Zabiullah Mujahid took responsibility for the attack in an online statement, claiming that 49 policemen and six of their international trainers were killed, and 57 others were injured.
