PM Manmohan Singh is likely to visit Kokrajhar tomorrow, officials said, amid reports that the clashes between Bodo tribals and the Bengali-speaking Muslims had spread to Baksa district. The administration rushed more security forces to Baksa yesterday after gunmen fired on a group of people injuring three.

Baksa district shares a contiguous landscape with Kokrajhar and Chirang districts. Kokrajhar and Chirang remain the worst hit. Both districts have become a cauldron of communal tension.
