The Associated Press, citing police and rescue officials, reported that two express trains collided in Sindh, killing at least 25 passengers.

According to the Associated Press, police and rescue officials said that two express trains collided in southern Pakistan, killing at least 25 passengers.

Earlier on Monday, Usman Abdullah, a police officer in the Ghotki district of Sindh province, said that the Mira Express derailed and the Sir Said Express crashed into it shortly afterwards.

He said that villagers, rescuers and police are taking the dead and injured passengers to a nearby hospital.

It is unclear what caused the derailment and subsequent collision.

Train accidents are common in Pakistan, and successive governments have paid little attention to improving poorly maintained signal systems and aging tracks.
