Two passenger trains collided head-on Sunday in the east of India, killing at least one person. The number of injured is unclear, and more casualties are feared.

The accident occurred in West Bengal province. The engine of the Guwahati-Bangalore express derailed as it collided with a local train. The two engines then caught fire.

After the initial collision, additional train carriages reportedly derailed. Rescue officials have been rushed to the scene.

Sunday's crash comes three weeks after two passenger trains derailed in separate incidents on the same day, leaving at least 67 people dead and about 200 others injured. All of the fatalities occurred in a derailment in the northern state of Uttar Pradesh.
