The Bodo tribes living in Assam celebrated their spring festival ‘Baisagu’ with traditional gaiety and enthusiasm on Saturday. Attractive cultural programmes and tribal dances marked the occasion in four Bodo-dominated districts of Kokrajhar, Udalguri, Baksa and Chirang. While in rest parts of the State, the people celebrated Rongali Bihu to welcome the Assamese New Year 1419 which began today.
