A bomb exploded at a busy bus terminal near of the Pakistani capital on Monday, reportedly killing 12 people and wounding several more, officials said.

The blast in Rawalpindi came as Pakistan's leaders sought to end a political crisis that has raied doubts about their focus on fighting Taliban and Al Qaeda militants.

TV images showed rescue workers helping the wounded to ambulances while gloved investigators pick debris from a darkened street among several badly damaged cars and minibuses.

City police officer Anaytullah Farooqi said the bomb appeared to have gone off in one of the vehicles.
