A spokesman for a separatist ethnic group in India says Burma has launched a military offensive aimed at driving the rebels out of their training bases in northeastern Burma.
The rebels' spokesman speaking to reporters by telephone from Guwahati, India says there have been sporadic clashes since Saturday between fighters from the separatist group the National Socialist Council of Nagaland and about three-thousand Burmese troops.
Government officials in Burma have promised India they will shut down the Naga separatists' camps in Burma.
India's Naga rebels say they have been fighting to protect their ethnic identity and to advance their campaign for a homeland separate from India.
