suicide bomber was in police uniform: Pakistan Blast

The suicide bomber who killed more than hundred people inside a mosque in Pakistan was wearing a police uniform and helmet, a police chief said Thursday.

"Those on duty didn't check him because he was in a police uniform... It was a security lapse," Moazzam Jah Ansari, the head of Khyber Pakhtunkhwa province police force, told a news conference.

Authorities are investigating how a major breach could happen in one of the most sensitive areas of the city, which houses intelligence and counter-terrorism bureaus and is next door to the regional secretariat.

Hundreds of police officers were attending afternoon prayers inside the mosque in the northwest city of Peshawar on Monday when the blast erupted.
