According to the agency, the tanker was detained in connection with the violation of international rules.

On July 4, Royal Marines of Great Britain detained off the coast of Gibraltar the tanker Grace 1, belonging to Iran, due to the fact that the ship allegedly delivered oil to Syria.

Iranian Defense Minister Amir Khatami said that Britain’s detention of an Iranian tanker off the coast of Gibraltar is "maritime piracy."
