TEHRAN: Iran`s Revolutionary Guards said on Saturday that they had seized an oil tanker in the Gulf off the country`s coast, a day after security companies determined they were likely responsible.

`Yesterday morning at 7.30, after a judicial authority ordered the seizure of the cargo of an oil tanker with the trade name Talara and the flag of Marshall Islands, the Islamic Revolutionary Guard Corps (IRGC) rapid reaction units of the naval forces monitored its movements and intercepted and seized it,` said a statement from the IRGC, the ideological arm of Iran`s military.

`The tanker was found to be in violation of the law by carrying unauthorised cargo,` the statement continued, adding it `was carrying 30,000 tonnes of petrochemical cargo and was heading to Singapore`.

The vessel had departed from Ajman, United Arab Emirates, and was heading south through the Strait of Hormuz when it was approached by three small boats, after which it made a `sudden course deviation`, maritime security company Ambrey said.

The US Navy had earlier said it was `actively monitoring the situation`. `Commercial vessels are entitled to largely unimpeded rights of navigation and commerce on the high seas,` said the US Fifth Fleet, which patrols the region.-AFP
