Balasore, Orissa, Mar 23: India's first intermediate range ballistic missile ''Agni'' was successfully test-fired from the Wheeler island, close to the Orissa coast, today.

The surface-to-surface missile, described as Agni I variant, was test-fired at 1005 hrs from a mobile launcher from the inner Wheeler island, sources said, adding it had achieved the mission target.

The two-stage Agni incorporates a slightly modified Augmented Satellite Launch Vehicle (ASLV) design in its second stage. The missile was first test-flown on May 22, 1989, from the Interim Test Range (ITR) at Chandipur-on-sea, about 15 km from here.
