The collision happened in Andhra Pradesh state's Vizianagaram district when an incoming passenger train hit a stationary train.

At least three rail carriages were derailed, according to officials.

Several rescue teams and local residents assisted injured passengers by extracting them from the wreckage.

Chief minister of Andhra Pradesh, YS Jagan Mohan Reddy, asked for as many ambulances as possible to be sent to the crash site.

It follows one of the country's deadliest rail crashes in decades back in June.

More than 280 people were killed when two passenger trains collided in the east of the country.
