TEHRAN (Reuters/AFP) - Iran on Monday test-fired long-range missiles it says could reach targets inside Israel, flexing its military muscle before crucial talks this week with major powers worried about Tehrans nuclear ambitions. The defiant Revolutionary Guards stagedwar games amid tension with the West over Tehrans atomic drive. Revolutionary Guards air force commander Hossein Salami said his men successfully test-fired surface-to-surface Sejil and Shahab-3 long-range missiles on the second straight day of the manoeuvres. An improved version of Shahab-3 and the two-stage Sejil, powered by solid fuel, were fired, Salami was quoted as saying by state-owned Arabic language Al-Alam television. Salami issued a stern warning to Irans foes. Our response will be strong and destructive to those who threaten the existence, independence, freedom and values of our regime. They will regret it, the official IRNA news agency quoted him as saying. The Fars news agency said it was the first time the Sejil had been test-fired during a military exercise. Television footage of the launches showed missiles soaring into the sky in desert-like terrain, to shouts of Allahu Akbar (Allah is the Greatest). The missile drills of the elite Revolutionary Guards coincide with escalating tension in Irans nuclear dispute with the West, after last weeks disclosure by Tehran that it is building a second uranium enrichment plant. News of the nuclear fuel facility south of Tehran added urgency to the rare meeting in Geneva on Thursday between Iranian officials and representatives of six major powers, including the United States, China and Russia. Irans Foreign Ministry said there was no link between the missile manoeuvres and the nuclear activities. This is a military drill which is deterrent in nature, spokesman Hassan Qashqavi told a news conference broadcast by English-language Press TV. There is no connection whatsoever with the nuclear programme. Iran says both long-range weapons can travel for 2,000km, which would put arch-foe Israel, most Arab states and parts of Europe, including much of Turkey, within range. All targets within the region, no matter where they are, will be within the range of these missiles, said Gen Hossein Salami, commander of the Guards air force. Salami said the exercise was over and had achieved its goals. All the test-fired missiles managed to hit their targets without any errors and with precision, the forces website quoted him as saying. Irans state broadcaster IRIB said upgraded versions of Shahab 3 and another missile, Sejil, had been tested. Officials have earlier said Sejil has a range of close to 2,000km. They were powered by solid fuel, IRIB said. The medium-range Shahab-1 and Shahab-2, with a range of between 300km and 700km, were successfully launched, Salami said. The missiles shot have precisely hit the targets, he added. Earlier, the Guards test-fired three types of short-range missiles - the Tondar-69, Fateh-110 and Zelzal. All three solid-fuel weapons have a range of between 100 and 400 kilometres.
