Two bombs exploded on a river ferry at Mallya. The explosion killed a passenger and seriously injured the skipper of the ferry. The survivors swam ashore but the armed Muslim settlers were waiting for them and attacked the indigenous Chakma Buddhists - men women and children.

Bangladeshi armed forces launched military campaigns in the upper reaches of the Sengu river from November 1976 to January 1977 and destroyed many villages in the areas of Madhu and Thanchi. Over 1,000 indigenous people were killed, hundreds of women were raped, and their villages and farmlands were distributed to the Muslim settlers.

About 15,000 indigenous people took refuge in Burma and in the neighbouring forests.
