Pakistani police say at least 19 people have been killed and 35 injured when two buses collided in eastern Punjab province.

Officer Imran Yaqoob says the collision took place Sunday night over a bridge near the city of Dera Ghazi Khan and that death toll could increase as many of the injured are in critical condition.

Yaqoob said both buses were speeding when they collided. He added that most of the victims, including women and children, were from one extended family traveling from Dera Ghazi Khan to Multan.

Traffic accidents are common in Pakistan where motorists largely disregard traffic rules and ignore safety standards.
