MNA � The Guardian Council Spokesman Abbasali Kadkhodaei said that Iran�s measure to seize a trespassing British oil tanker was carried out according to the rule of retaliation in the international law.

�The rule of retaliation is a recognized concept in international law and it is used in the face of another country�s illegal measures. The correct action of Iran�s government to encounter illegal economic war and seizure of oil tankers is an example of this rule and it is carried out according to the international law,� Kadkhodaei tweeted on Saturday.

In a statement on Friday, the IRGC said that the vessel named �Stena Impero� had been captured �at the request of Hormozgan Ports and Maritime Organization when passing through the Strait of Hormuz, for failing to respect international maritime rules.� The oil tanker was transferred to the coast to undergo the required legal proceedings, the statement added.

An unnamed Iranian maritime official said the ship had breached international maritime regulations by passing through a prohibited maritime passage in the Strait, turning off its tracking signals and ignoring warnings issued by Iranian authorities. "The tanker had turned off its tracker and ignored several warnings by the IRGC before being impounded," the source said.

On July 4, British Royal Marines in Gibraltar stormed the Iran-operated 300,000-tonne Grace 1 and detained it, accusing it of carrying oil to Syria in possible violation of the European Union�s sanctions on the Arab country. Iran condemned the move as �piracy� and summoned Britain�s ambassador in protest over it.
