According to the unofficial reports, Jamaran – operated by Iran’s Revolutionary Guards Corps (IRGC) – fired the missile prematurely before Konarak had time to sail away from a floating target it had towed to a designated position.
Videos posted on social media show what are said to be injured sailors being transferred to ambulances.
In January, the IRGC mistakenly shot down a Ukrainian passenger plane near Tehran, killing all 176 people on board. The incident came at a time of heightened tension with the US. Shortly before, Iranian had launched a missile strike on an Iraqi base hosting US forces after an American drone strike killed IRGC commander Qasem Soleimani in the Iraqi capital Baghdad.
These tensions have continued to rise in recent months. The US has accused Iran of “harassing” its naval ships in the Persian Gulf.
Iran said said it had increased patrols in the Gulf after the US Navy blocked the path of an Iranian vessel.
