Two passenger trains derailed Friday in India, killing more than 200 people and trapping hundreds of others inside more than a dozen damaged rail cars, officials said.

The accident that happened about 220 kilometers (137 miles) southwest of Kolkata created a chaotic scene of twisted wreckage and desperate rescuers as teams tried to free passengers and recover bodies. The cause was under investigation.

About 900 people were injured in the accident, P.K. Jena, the top bureaucrat in the eastern state of Odisha, said in a tweet.

Ten to 12 coaches of one train derailed, and debris from some of the mangled coaches fell onto a nearby track, said Amitabh Sharma, a railroad ministry spokesperson.

The debris was hit by another passenger train coming from the opposite direction, and up to three coaches of the second train also derailed, Sharma said.

The Press Trust reported that a third train carrying freight was also involved, but there was no immediate confirmation from railroad authorities. The Press Trust report said some of the derailed passenger coaches hit cars from the freight train.

The death toll rose steadily throughout the night. As dawn approached on Saturday, Jena said that at least 233 people were dead.

In the aftermath, television images showed rescuers climbing atop the wreckage to break open doors and windows and using cutting torches to free survivors.

Officials said 1,200 rescuers worked with 115 ambulances, 50 buses and 45 mobile health units through the night at the accident site.

Villagers said they rushed to the site to evacuate people after hearing a loud sound created by the train coaches going off the tracks.
