Iranian state television says the country has fired a series of missiles as part of an ongoing large-scale military maneuvers in the Persian Gulf and Strait of Hormuz.
The TV report Sunday said five ground-to-sea and sea-to-sea missiles were simultaneously fired.
It did not elaborate on the specifications of the missiles or say whether they are new.
However, the semiofficial Fars news agency said on Saturday that four types of short-range missiles would be launched Sunday in the war games, including Nasr 1, a short-range cruise capable of destroying targets up to 3,000 tons in size.
Iran's Revolutionary Guard began the war games, an annual show of military strength that often leads to heightened tension in the region, on Thursday.
