At least 13 people have died and about 50 are injured after two passenger trains collided in India’s southern Andhra Pradesh state on Sunday.
A rescue operation was launched and hundreds of emergency workers were at the site to clear the wreckage.
Officials said a preliminary investigation has found that a “human error” had led to the collision.
Prime Minister Narendra Modi expressed his condolences and said he was in touch with the railways minister.
