GUWAHATI, India (Reuters) - At least 10 Kuki tribespeople, including two women and two babies, were killed by a rival ethnic group in India's mountainous northeastern state of Manipur, police said on Tuesday. The tribals were killed on Monday by Paitie tribesmen in a remote village in the Churachandpur district. Ten other people were injured in the incident and taken to hospital, police said. Police and army personnel have tightened security around the area following the killings and are combing the region to find the tribesmen responsible for the killings. Last month, 14 Kuki tribals were killed by a rival tribe which attacked two villages, torching dozens of homes on the eve of India's general elections. Hundreds of tribals have died since 1993 in the state in a series of bloody ethnic clashes, which have also been fired by drives for separatism and a jostle for control of a lucrative drugs trade. In the second half of 1997 alone, ethnic violence between Manipur's complicated patchwork of tribes -- Naga against Kuki, Kuki against Waifes and Kuki against Paitie -- claimed the lives of three hundred people. Kuki and Paitie tribesmen are formidable mountain warriors fighting over the same territory as their homeland. Kukis are migrants from neighbouring Myanmar (Burma) who have settled in the highlands of Manipur.
