Iran on Monday test-fired its long-range Shahab-3 missile. The exercise comes at a time of heightened tension with the West after the UN nuclear watchdog said on Friday that the Islamic republic was building a second uranium enrichment plant. Iran's English-language state-owned Press TV channel on Monday broadcast footage of the Shahab-3 being fired in desert terrain. Iran says the weapon has a range of 1,300-2,000 kilometres, which would put Israel, most Arab states and parts of Europe including much of Turkey within its range.The state media reported that the Guards on Sunday fired several short and medium-range missiles, some with multiple warheads. The Guards' air force commander Hossein Salami said, the medium-range Shahab-1 and Shahab-2, with a range of between 300 kilometres and 700 kilometres, were successfully launched. Earlier, the Guards test-fired three types of short-range missile, the Tondar-69, Fateh-110 and Zelzal. All three weapons, powered by solid fuel, have a range of between 100 and 400 kilometres.
