At least 10 people died in India's eastern Assam state in attacks by armed groups from a neighboring Indian state over alleged land dispute, local police said. Police said armed groups from neighboring Arunachal Pradesh attacked Chauldhuwa, a border village in a forest area in Assam's Sonitpur district, leaving at least 10 dead and another eight injured. The Times of India said tensions over a boundary dispute have been simmering for decades. "People from Arunachal attacked a village in our state. We are sending additional forces there," a Sonitpur police official was quoted as saying. The Calcutta Telegraph quoted police as saying the attackers fired on a group of people from the Assam side as they tried to stop the attackers from encroaching on their land.
