A suicide bomber, possibly a teenager, killed at least 13 people and wounded about 40 in a Shiite Muslim seminary on the edge of Pakistan's northwestern city of Peshawar on Friday, officials said.
Though no group has claimed responsibility for the bombing, it's the third major attack since the Taliban vowed revenge for a US drone strike that killed its deputy commander, with more than 60 people now dead in less than a week.
Reports say three unidentified assailants entered the mosque and shot and critically wounded an on-guard policeman. "The bomber was brought by two other persons who shot dead the security guard," police chief Shafiullah Khan said.
The three men then entered the mosque, where one detonated a suicide vest. The two other militants escaped and a manhunt is in progress.
Witness Zawar Hussain said there were about 300 worshippers inside, adding that "after the blast, I fell down. People were crying for help. I saw bodies and badly injured worshippers everywhere."
President Asif Ali Zardari condemned the “cowardly and heinous act” in a statement.
Also Friday, unidentified gunmen killed a provincial lawmaker and his son in the southern city of Karachi.
