At least 50 people have died and hundreds of others have been injured after three trains were involved in a crash in eastern India.
A passenger train derailed and collided with another passenger service which then hit a goods train in Odisha's Balasore district on Friday evening.
The cause of the crash is being investigated.
Rescuers were attempting to free 200 people feared trapped in the derailed carriages, said D B Shinde, the Balasore district administrator in Odisha state.
The Coromandel Express, which runs from Kolkata to Chennai, derailed after the collision and fell on the opposite track.
Dattatraya Bhausaheb Shinde, the top administrator in the Balasore district, said at least 50 people were dead.
Nearly 500 police officers and rescue workers with 75 ambulances and buses responded to the accident, said Pradeep Jena, Odisha's chief secretary.
India's Prime Minister Narendra Modi said he is "distressed" by the accident and said rescue operations are under way at the site.
Photos from the scene show people trying to escape from a toppled carriage.
A railroad ministry spokesperson, Amitabh Sharma, said mangled pieces of the derailed train fell on to a nearby track and were hit by another passenger train coming in the opposite direction.
More than 12 million people ride 14,000 trains across India every day, traveling on 40,000 miles of track.
Despite government efforts to improve rail safety, several hundred accidents occur every year on India's railways, the largest train network under one management in the world.
Most train accidents are blamed on human error or outdated signaling equipment.
