An official Iranian news agency says Iran is sending a submarine and a warship to the Gulf of Aden and the Red Sea.
Press TV quotes the commander, Rear Adm. Habibollah Sayyari, as saying the deployment will serve the country's interests and "convey the message of peace and friendship to all countries."
The item on Press TV's website Tuesday said the presence of the Iranian navy would "tighten security for all countries."
Sayyari said the ships would also fight against pirates.
Somalia, on the southern coast of the Gulf of Aden, is a base for many pirate gangs. The body of water is south of Iran.
