GAUHATI, India (AP) _ Suspected separatist guerrillas killed 19 Bengali settlers in a tribal-dominated state in northeastern India, police said Wednesday.

Eight other settlers were wounded in the attack late Tuesday near the village of Simnachara in Tripura state, where several tribal groups have been fighting to evict tens of thousands of migrants from the neighboring state of West Bengal.

No group immediately claimed responsibility, but police blamed the attack on the All Tripura Tiger Forces, an outlawed rebel group that has been fighting for a separate tribal homeland.

The tribal groups accuse the Bengali settlers of exploiting Tripura's resources and depriving its native population of the benefits of economic development.

Simnachara is about 15 miles north of Agartala, Tripura's capital.
