Iran has test-fired a surface-to-surface cruise missile during a drill in international waters near the strategic Strait of Hormuz, the country's navy said.
The official IRNA news agency said the missile, called "Ghader" or "Capable" in Farsi, is an upgraded version of one that has been in service before.
The report did not elaborate. An earlier version of the missile had a range of 124 miles and could travel at low altitudes. There were suggestions it could be used to counter the US naval presence in the Persian Gulf.
The report said two more missiles would be tested.
Iran said on Sunday it test-fired an advanced surface-to-air missile during the drill. An Iranian politician said the manoeuvres serve as practice for closing the strait if the West blocks Iran's oil sales.
