The incident occurred on Tuesday morning at a train station in Brahmanbaria District in eastern Bangladesh. The Udayan Express train was approaching a platform when it collided with another train. As a result of the collision, at least two railway cars were seriously damaged.
A local police spokesman said a rescue operation was underway at the site, and the death toll might increase.
Earlier in the year, five people were killed and 100 more injured as several carriages of a train fell off a bridge in the Moulvibazar district, in the north of Bangladesh.
