A video showing visuals of charred bodies is in circulation on social media platforms with the claim of it being the incident from the Birbhum district of West Bengal in which eight people, including three women and two children, were burnt alive.
The incident took place after the murder of a local TMC leader on Monday evening, 21 March. According to news reports, at least 20 people have been arrested in connection with the incident.
However, Facto News in its verification found that the claim along the viral video is misleading. The video is from 2020, of a bus accident from Odisha.
The caption along with the viral video reads: “#ममता बानो की TMC के गुंडों ने कल बंगाल* में 10 महिलाओं और 2 बच्चों समेत 12 आदिवासी हिंदुओं को जिंदा जला दिया है। ग्रुप में अब वो लोग ये खबर विधिवत विस्तार से क्यो नही पोस्ट कर रहे हैं ????, जो सत्ताधारी सत्ताधारी चिल्ला रहे थे !!!!!”
(Translation: Mamta Bano TMC goons have burnt alive 12 tribal Hindus including 10 women and 2 children in Bengal yesterday. Why are the people in the group now not posting this news in proper detail?)

FactO News:
We extracted the keyframes of the video and performed a reverse search of them. The result led us to a video report published on 9 February 2020 by the YouTube channel Asian Times. The video carries similar visuals of a blue coloured bus as seen in the viral video. It also says that the bus had caught fire by coming in contact with high power electric wire.
Taking a cue from this we further searched about the incident by using relevant keywords. According to a report carrying the image of the same blue coloured bus published in The Times of India on 9 February 2020, at least 9 people were killed and 35 injured in the Ganjam district of Odisha after the bus had come in contact with an electric transmission line.
