Iran reportedly detained a United Arab Emirates-flagged vessel after the Emirati forces killed two Iranian fishermen earlier in the week.

UAE authorities said on Tuesday that eight fishing vessels illegally entered Emirati territorial waters the day before near Sir Bu Nair Island, roughly 100 km west of Dubai.

A patrol from the country's coastguard attempted to stop the vessels and, when ignored, "rules of engagement were applied". This was identified on Thursday by Iran state-linked media as gunfire, which killed two of the fishermen.
