Suicide attack kills 18 policemen in Afghan

A suicide attacker wearing police uniform detonated at a police station in Afghanistan's province of Uruzgan on Monday, killing at least 18 police officers, authorities said.

"In the suicide blast, 18 policemen were martyred and several others were wounded," Juma Gul Himat, the provincial police chief, said.

Policemen at the reserve unit in the provincial capital, Tirin Kot, had been getting ready to stand in line for the morning exercise when the suicide bomber set off explosives strapped to his body, he said.

It was not immediately clear if the attacker was a policeman from the unit or someone who had managed to acquire a uniform and infiltrate his way into the crowd, Himat said.
