As many as 19 Iranian sailors are dead and at least 15 injured after a rocket fired during a training exercise in the Gulf of Oman hit a ship near the port of Jask, around 1,270 kilometres south-east of Tehran.
Iranian media confirmed Monday that the rocket had hit the Konarak, which was tasked with putting targets in the water for other ships to fire upon. At least 12 sailors were admitted to hospital, with a further three treated for minor injuries.
Iran initially said one sailor had been killed on Monday but then hours later updated the death toll to 19.
A Dutch manufactured vessel that was given the capability to fire sea and anti-ship missiles in 2018, the Konarak had been in service for more than 30 years and usually carries a crew of 20 sailors.
