Oct. 28: Vehicles and shop fronts are seen in flames after the massive explosion in Peshawar, Pakistan.

PESHAWAR, Pakistan —  A massive car bomb rocked a women’s market in Pakistan’s main northwest city of Peshawar on Wednesday, killing at least 57 people in the latest attack to shake the country as the army battles Islamist militants along the Afghan border.

The death toll was expected to rise further as local media reported “scores” buried in rubble.

At least 100 other people were wounded in the blast, a doctor said. It coincided with a trip to Pakistan by U.S. Secretary of State Hillary Rodham Clinton, who was in the capital, Islamabad, some three hours drive away.
