DUBAI — The United States on Monday said it was setting up an international maritime coalition to counter escalating attacks by Yemen’s Houthi rebels on vital Red Sea shipping lanes. “These attacks are reckless, dangerous, and they violate international law,” US Defence Secretary Lloyd Austin told a news conference during a visit to Israel. “We’re taking action to build an international coalition to address this threat,” Austin said. “This is not just a US issue. This is an international problem, and it deserves an international response.” He said a virtual meeting on Tuesday would bring together ministers from Middle Eastern countries to address the issue, and warned Iran to stop supporting the Houthi attacks. Yemen’s Iran-backed Houthi rebels said earlier they had attacked two “Israeli-linked” vessels in the Red Sea in solidarity with Gaza, as more companies halt transit through the troubled but vital waterway. The attacks on the Norwegian-owned Swan Atlantic and another ship identified by the Houthis as the MSC Clara are the latest in a flurry of maritime incidents that are disrupting global trade in an attempt to pressure Israel over its war against Hamas fighters. In a statement, the Yemeni rebels said they had carried out a “military operation against two ships linked to the Zionist entity” using naval drones. They vowed to “continue to prevent all ships heading to Israeli ports… from navigating in the Arab and Red Seas” until more food and medicine is allowed into Gaza. But the Swan Atlantic’s owner, Norway’s Inventor Chemical Tankers, said in a statement the ship was carrying biofuel feedstock from France to Reunion Island. It said the vessel has “no Israeli link” and was managed by a Singaporean firm, adding that the Indian crew were unharmed and the vessel sustained limited damage. British oil giant BP became the latest to suspend transit through the Red Sea on Monday, while Taiwan shipping firm Evergreen said it was suspending its Israeli cargo shipments with immediate effect. Frontline, one of the world’s largest tanker companies, also said it was rerouting ships and would “only allow new business” that could be routed via South Africa’s Cape of Good Hope. That route is far longer and uses more fuel. The Red Sea attacks have forced insurance companies to significantly increase premiums on ships, making it uneconomical for some to transit through the Suez Canal. Italian-Swiss giant Mediterranean Shipping Company, France’s CMA CGM, Germany’s Hapag-Lloyd, Belgium’s Euronav and Denmark’s A.P Moller-Maersk, the latter accounting for 15 per cent of global container freight, have all stopped using the Red Sea until further notice. The attacks have become “a maritime security crisis” with “commercial and economic implications in the region and beyond”, Torbjorn Soltvedt of analysis firm Verisk Maplecroft told AFP. Monday’s attack took place as the Pentagon chief visited Israel after a stop in Bahrain, home base of the US Navy’s Fifth Fleet. “In the Red Sea, we’re leading a multinational maritime taskforce to uphold the bedrock principle of freedom of navigation. Iran’s support for Houthi attacks on commercial vessels must stop,” Austin said. On Saturday, a US destroyer shot down 14 drones in the Red Sea launched from rebel-controlled areas of Yemen, the US military said. Britain said one of its destroyers had also brought down a suspected attack drone in the area. Rebel spokesman Mohammed Abdul Salam said neutral Oman had launched mediation efforts to safeguard shipping using the waterway. “Under the sponsorship of our brothers in the Sultanate of Oman, communication and discussion continue with a number of international parties regarding operations in the Red Sea and Arabian Sea,” he said on X, formerly Twitter.
