At least 80 people are now known to have been killed and 850 injured in a multiple train collision in India’s eastern Odisha state, officials say.
More than 200 ambulances were sent to the scene in Balasore district, says Odisha’s chief secretary Pradeep Jena.
One passenger train is thought to have derailed before being struck by another on the adjacent track late on Friday.
Indian Railways said the two services involved were the Coromandel Express and the Howrah Superfast Express.
“So far 850 injured [have been] sent to hospital. Around 80 deaths [are] reported,” Mr Jena said in a tweet.
He said more than 100 additional doctors have been mobilised, adding that rescue efforts were “in full swing”.
Indian Prime Minister Narendra Modi said he was distressed by the incident, and his thoughts were with the bereaved families.
