Pakistani police say a speeding bus has plunged into a fast-flowing river in Pakistan's part of Kashmir, killing at least 24 passengers.

Local police official Aslam Khan said the bus fell into the Neelum river Friday night and rescuers had so far found only four bodies.

He said the other bodies have been swept away by the water and search efforts were underway.

Khan said a lone survivor told rescuers that 25 passengers were aboard when the bus fell into the river about 50 kilometers (30 miles) north of Muzaffarabad, the capital of Pakistan's part of Kashmir.

Deadly accidents are common in Pakistan, mainly because of bad road infrastructure and reckless driving habits.
