TEHRAN, Iran, (AP) - Iran on Sunday test-fired a sub-to-surface missile in the Persian Gulf during large-scale military exercises, state-run television reported.

"The army successfully test-fired a top speed long-range sub-to-surface missile off the Persian Gulf," the Army's Navy commander, Gen. Sajjad Kouchaki, said on state television.

A brief video clip showed the missile, fired from a submarine, hitting a target on the surface of the water within less than a mile.

The test came as part of large-scale military exercises under way throughout the country. Iran has routinely held war games over the past two decades to improve its combat readiness and to test equipment including missiles, tanks and armored personnel carriers.
