Commenting on the incident, the UK government said that it is concerned by this action, and it urges the Iranian authorities to de-escalate the situation in the region.

The incident comes only a week after British Royal Marines boarded an Iranian tanker, Grace 1, off Gibraltar, seizing the ship, as they suspected that it was violating sanctions by transporting oil to Syria.

Following seizure of the oil tanker 'Grace 1', 'British Heritage', run by oil major BP, was being kept inside the Persian Gulf, off Saudi Arabia, in fear it could be seized by Iran for retaliation.
