Iran on Thursday ended its large-scale military exercises by test-firing a 2,000-pound guided bomb, state-run television reported.

"It is a flying bomb and can be used as a guided long-range air-to-surface missile," Gen. Amir Amini, deputy commander of Iran's air force, told state TV.

Amini added that the bomb was a special weapon developed for penetrating military, economic and strategic targets located deep underground on the soil of the enemy.
