Iran has launched a new, domestically made submarine equipped with what it says is the latest military and technological equipment.
According to official media, the submarine has been named Ghadir - after a Muslim holiday of the same name.
State media in Tehran broadcast pictures Wednesday of a submersible craft, but it was not immediately clear if it was the new one, or a craft previously shown by Iranian media.
In 2005, Iran announced that it had built its first sub.
Iran has been praising its military prowess of late, amid increasing tensions over its nuclear program. The United States says Tehran's program is a cover to build a nuclear weapon. Tehran denies the charge, saying its program is for peaceful purposes only.
