A minibus packed with explosives detonated along a road near a market in Pakistan's northwestern city of Peshawar on Friday, killing scores of bystanders. Officials said 41 people were killed and more than 100 wounded.
The attack comes just days after a suicide attack killed five at a UN office in the capital, Islamabad, and as Pakistan's army prepares for a potential new operation in the South Waziristan tribal region, a major base for the Taliban and al-Qaida.
Two weeks earlier, another blast in a Peshawar commercial district left 11 dead. Friday's attack demonstrates the continuing ability of militants to strike Pakistan's major cities.
