At least 30 people were injured when a freight train and a passenger train collided in eastern Pakistan early Sunday.

Authorities say an investigation has been launched and that one train’s driver, his assistant and two other workers have been suspended following the collision.

Railway official Shahid Aziz said the incident happened in Shaikhupura district near Qila Sattar Shah station. He said most of the injured passengers had been treated at the train station and those with more serious injuries had been transported to hospitals.

Railway crashes are common in Pakistan because of railways’ aging infrastructure.
