Security officials said today that the commander of a powerful rebel movement in India’s remote northeast has surrendered with a top deputy.

A bomb exploded today in a crowded vegetable market in the Indian state of Assam, killing at least four people and leaving eight injured, police said.

Suspected rebels woke up sleeping villagers in north-eastern India and opened fire with automatic weapons, killing six of them and raising the death toll to 63 from three days of violence in a region where dozens of ethnic rebel groups are fighting for separate homelands.
