Iran said on Saturday it seized a British-flagged oil tanker because it was involved in an accident, but Britain’s foreign minister said he feared Tehran was taking “a dangerous path” and other major European powers expressed alarm.

Axar.az reports citing Reuters that Iran’s elite Revolutionary Guards took control of the Stena Impero in the Strait of Hormuz on Friday after it collided with an Iranian fishing boat whose distress call it ignored, the Fars news agency reported.

The vessel and its crew would remain in the Iranian port of Bander Abbas while the accident was investigated, it said, quoting the head of Ports and Maritime Organisation in southern Hormozgan province, Allahmorad Afifipour.

France and Germany joined Britain in condemning the seizure.
