Iran's Revolutionary Guards fired missiles able to carry cluster warheads at the start of 10 days of military maneuvers on Thursday, state television said. Tehran had said the maneuvers, which will last until November 11 and include drills in the Gulf and Sea of Oman, would be a show of "defensive strength". "Dozens of missiles were fired including Shahab-2 and Shahab-3 missiles. The missiles had ranges from 300 km up to 2,000 km," Iranian state television reported, without showing any footage. A reporter for state-owned Arabic-language Al-Alam television earlier told Reuters from central Iran, near where he said the missiles were fired, that Shahab-3 missiles could carry cluster warheads. State television confirmed this. "Iranian experts have made some changes to Shahab-3 missiles installing cluster warheads in them with the capacity to carry 1,400 bombs," state television said. It did not say whether the unarmed missiles fired were carrying warheads at the time. Experts say Iran's Shahab-3 missiles have a maximum range of some 2,000 km.
