Two Iranian Revolutionary Guard Corps (IRGC) gunboats have opened fire on a tanker in the Strait of Hormuz, according to the UK’s maritime security monitoring service.
On Saturday morning, the UK Maritime Trade Operations Centre (UKMTO) said the tanker and crew were reported safe.
Its map places the attack off the north-west coast of the United Arab Emirates.
The UKMTO, which provides the primary liaison between military authorities and merchant vessels, said authorities are investigating.
It is understood the tanker is not a UK-flagged vessel.
Earlier on Saturday, Iran announced it had re-imposed restrictions on the vital waterway after the US said reopening the strait would not end its blockade of Iran-linked shipping.
