Iranian authorities announced that the warship "Sahand" encountered an "accident" in the port of Bandar Abbas in southern Iran, capsized, and sank.
The Iranian news agency IRNA reported the incident, but did not provide details about casualties, nor about other ships that led to the warship's sinking in the port.
The destroyer "Sahand" is one of the most modern vessels of the Iranian navy, which suffers from obsolescence after decades of international sanctions.
The "Sahand" is a missile-carrying destroyer built by the Iranian Navy's Factories and entered service in 2012.
