A massive suicide bombing Wednesday flattened a three-storey police station in Pakistan's restive northwestern city of Peshawar, killing two officers and wounding 19 people, officials said.
"Two police were killed and 19 people wounded," said Liaqat Ali Khan, chief of police in Peshawar.
Senior police officer Mohammad Ijaz told AFP that the bomber drove his explosives-laden car into the Criminal Investigation Department police station in the Peshawar Cantonment area.
There was no immediate claim of responsibility, but Pakistan's Taliban have carried out three bloody attacks to avenge the killing of Al-Qaeda leader Osama bin Laden by US commandos north of Islamabad on May 2.
