An outlawed separatist group has announced a unilateral cease-fire in northeast India in hopes of making further progress on a peace agreement with the government.

The leader of the United Liberation Front of Asom , also known as ULFA, called on all members to adhere to the agreement and said Tuesday the cease-fire will continue for an indefinite period.

Indian authorities have not yet responded.

An ULFA splinter group, headed by commander Paresh Baruah, is not participating in the peace talks.

ULFA has been fighting for more than three decades in pursuit of an independent homeland for the ethnic Assamese in India's northeast.

The fighting has killed at least 10,000 people, mostly civilians.
