At least seven people were killed and 24l others injured after 11 coaches of a New Delhi-bound train derailed in India's eastern Bihar state on Sunday.
East Central Railway general manager, L.C. Trivedi, said rescuers were searching for the coaches for people who may be trapped inside.
The cause of the accident has yet to be identified.
Local media reports said that a rail fracture may have led to the derailment of Seemanchal Express that took place about 30 kilometers north of state capital Patna.
