Saudi Arabia, the United Arab Emirates (UAE), and Norway will present to the UN Security Council on Thursday the results of a joint probe into attacks targeting four tanker vessels off the UAE coast last month, diplomats said. The United States has accused Iran of being behind the attacks, which came at a time of escalating tensions between Tehran and Washington. US National Security Adviser John Bolton said on May 29 that they were the work of "naval mines almost certainly from Iran". Tehran denied the accusations. The May 12 attacks targeted two Saudi tankers, an Emirati vessel and a Norwegian tanker, causing no casualties. They occurred off the UAE emirate of Fujairah, which lies just outside the Strait of Hormuz, a vital global oil and gas shipping route. During an informal meeting at the UAE mission to the United Nations, Security Council ambassadors will be briefed on the evidence uncovered during the investigation, diplomats said. Saudi Arabia maintains that the attacks affect the safety of international navigation and the security of world oil supplies. — Agencies
