It said the missiles fired were of the Tondar and Fateh-110 type. A multiple missile launcher was also tested.

Iran's elite Revolutionary Guards announced on September 26 it would hold several days of military exercises over the next several days.

The tests come as tensions between Iran and the West are on the rise over Tehran's nuclear ambitions.

Earlier this week, Iran disclosed that it was building a second uranium enrichment plant.

President Mahmoud Ahmadinejad insisted that the plant, near the holy city of Qom, was being built in line with UN regulations. He also said it was open for inspection by UN experts.

US Secretary of State Hillary Clinton gave a cautious welcome to Iran's announcement that it would open the facility.

Leaders of the US, Britain and France have accused Tehran of building a new plant in breach of UN rules.

They raised the prospect of new, tougher sanctions against Iran if it does not fully co-operate with global powers.

Iran is due to meet with representatives of the so-called P5 + 1 on October 1 to discuss a range of issues, including its nuclear plans. The P5 + 1 groups together the five permanent members of the UN Security Council-the US, Russia, China, the UK and France-along with Germany.
