At least eight Indian soldiers were killed and at least five wounded when an army convoy was attacked by armed separatists in northeast India.
Indian police officials said on May 4 the militants opened fire on the troops before detonating a bomb during the attack in the remote Nagaland area near the border with Myanmar on May 3.
An official said four other soldiers are missing.
Police say the outlawed National Socialist Council of Nagaland, which has been fighting for decades for a homeland for Naga tribes, is suspected of carrying out the attack.
The militant group canceled a longstanding cease-fire last month after criticizing the Indian government for not being serious about the movement's demands.
India's seven northeastern states are home to dozens of tribal groups and their armed militias and have long been plagued by separatist violence.
