The tests were part of military exercises that began Wednesday in southern Iran, and all missiles successfully hit training targets at sea, the channel said.
Iranian military experts say the SSN-4 Sark missiles, designed in the 1960s in the Soviet Union and classified as R-13 missiles, have a hitting range of 300 km (186 miles) and are capable of reaching all classes of ships in the Persian Gulf and the Gulf of Oman, as well as in the northern part of the Indian Ocean.
On Wednesday Iran successfully tested a TOR-M1 air defense missile system recently supplied by Russia. In late January Russia delivered 29 TOR-M1 anti-aircraft missile systems to Iran under a $700 million contract signed at the end of 2005.
Russia's weapons supplies to Iran have alarmed the United States, which imposed new sanctions on the Russian government's official arms dealer Rosoboronexport and on two other companies for the sale of TOR-M1 to the Islamic Republic. Rosoboronexport faced sanctions for arms sales to Iran and Syria twice last year.
