PESHAWAR, Pakistan — A powerful bomb exploded inside a Shiite Muslim mosque in Pakistan’s northwestern city of Peshawar on Friday, killing more than 30 worshippers and wounding dozens more, many of them critically, police said.

Local police official Waheed Khan said the explosion occurred as worshippers had collected in the Kucha Risaldar mosque in Peshawar’s old city for Friday prayers. Ambulances rushed through congested narrow streets carrying the wounded to Lady Reading Hospital, where doctors worked feverishly.
