A suicide bomber who killed 101 people at a mosque in northwest Pakistan this week had disguised himself in a police uniform and did not raise suspicion among guards, the provincial police chief said on Thursday.
Moazzam Jah Ansari said the bomber had been identified and police were close to arresting members of the network that was behind Monday's attack, one of the deadliest ever in Peshawar, the capital in the Khyber Pakhtunkhwa province.
