Over 50 passengers are feared trapped in a bus that caught fire in Uttar Pradesh’s Kannauj district, India Today reported on Friday. The double-decker bus burst into flames after a collision with a truck on the highway, near Ghinoi village around 9.30 pm.

Several fire tenders have been rushed to the spot and are trying to douse the flames. There is no information yet on any casualties. The bus was on its way from Gursahaiganj in Kannauj to Jaipur in Rajasthan.

Uttar Pradesh Chief Minister Adityanath has taken cognisance of the matter, the state government said in a tweet. He has asked Kannauj District Magistrate Ravindra Kumar and Superintendent of Police Amrendra Prasad Singh to rush to the spot, and ensure that all possible medical attention is provided to the passengers, the government said.

“The fire tenders are trying to control the fire,” an unidentified police officer said, according to the Hindustan Times. “There could be casualties as people are inside. How many are in there or how many are hurt is not clear. It will be clear only after the fire comes under control. The bus was private and collided with the truck head-on.”
