Pakistan ? Suspected militants exploded a car bomb in a market crowded with women and children Wednesday, killing 105 people and turning shops selling wedding dresses, toys and jewelry into a mass of burning debris and bodies.

The attack in the northwestern city of Peshawar was Pakistan’s deadliest since 2007 and came as U.S. Secretary of State Hillary Rodham Clinton visited the country to offer support for its fight against a strengthening al-Qaida and Taliban-led insurgency based along the Afghan border.

Clinton was three hours’ drive away in the capital meeting Pakistani government leaders when the bomb went off in Peshawar. Her trip was not announced in advance in Pakistan for security reasons.
