Violent clashes have erupted between people in the Muslim community and tribespeople in the Birbhum district of India’s West Bengal state, police say.
Officials say at least 50 houses in three tribal villages were set on fire after a businessman from the Muslim community was murdered.
Tribal villagers retaliated with arrows and set fire to houses in Muslim areas.
Tribespeople are trying to stop illegal stone quarries opening – the murdered businessman was a quarry owner.
He had recently had a dispute with local villagers over the re-opening of his quarry.
"It is the stone quarry owners who are trying to provoke a Muslim backlash against the tribals because they are desperate to resume their illegal businesses in the area," alleged Kunal Deb, who heads a local non-governmental organisation.
