Iran test fired its second long-range missile during a naval exercise in the Gulf, state TV's website quoted a senior navy commander saying today.
"Today our Nour surface-to-surface long range missile was also successfully launched," said deputy navy Commander Mahmoud Mousavi.
Iran earlier successfully fired one long-range missile during its naval exercise in the Gulf, flexing its military muscle to show it could hit Israel and US bases in the region if attacked.
The announcement came amid rising tension over Iran's disputed nuclear programme which Western powers believe is working on developing atomic bombs.
Tehran denies the accusation and last week said it would stop the flow of oil through the Strait of Hormuz if the West carried out threats to impose sanctions on its oil exports.
"We have test fired a long-range shore-to-sea missile called Qader [capable], which managed to successfully destroy predetermined targets in the Gulf," Mr Mousavi told the official news agency IRNA.
Mr Mousavi said observers from the country's closest Arab ally, Syria, would attend the last day of its 10-day naval exercise.
The European Union is considering a ban - already in place by the United States - on imports of Iranian crude.
The US Fifth Fleet reacted to Iran's threat to stop oil flows, saying it will not allow any disruption of traffic in the Gulf.
The United States and Israel have not ruled out military action against Iran if diplomacy fails to resolve the Islamic state's nuclear row with the West.
Iran said it had no intention to close the Strait of Hormuz.
"No order has been given for the closure of the Strait of Hormuz. But we are prepared for various scenarios," state television quoted navy chief Habibollah Sayyari as saying.
