DUBAI- Saudi Arabia said on Tuesday that Iran's interception of commercial vessels, including its seizure of a British tanker, in Gulf waters was a violation of international law and urged the global community to deter such actions.

"Any disruption of the freedom of international maritime traffic is considered a violation of international law and the international community must do what is necessary to reject it and deter it," the Saudi cabinet said in a statement carried on state media.

Iran said on Friday it had seized Britain's Stena Impero tanker, which had been heading to a port in Saudi Arabia and suddenly changed course after passing through the Strait of Hormuz at the mouth of the Gulf.

Britain described the seizure as an act of "state piracy" and called for a European-led naval mission to ensure safe shipping through the world's most important oil artery.
