In Yemen, the Iranian-backed Houthi rebels declared a maritime embargo against Saudi Arabia on July 20, 2026. This decision was made in retaliation for a blockade on Yemen and a recent attack on Sanaa International Airport. The Houthi military spokesperson, Yahya Saree, stated that the embargo would be effective immediately, framing it as an 'eye for an eye' response to Saudi actions. The Bab al-Mandeb strait, a crucial waterway for global shipping, is now threatened, as it typically sees around 12% of the world's trade. The deputy head of the Houthi media office, Nasruddin Amer, emphasized that the strait would be closed due to Saudi Arabia's blockade on Yemenis, which has persisted for over a decade. This escalation raises concerns about renewed conflict in the region, especially given the Houthis' previous ability to disrupt shipping in the strait during the Israel-Hamas war, where they targeted over 100 vessels. Saudi Arabia, which leads a coalition against the Houthis and has imposed an air and sea blockade on Yemen since 2015, has not yet responded to this latest development. The situation is further complicated by the ongoing tensions in the region, including the use of the East-West Pipeline by Saudi Arabia as an alternative route for oil transport, as the Strait of Hormuz remains under Iranian control. The Houthis' recent missile and drone attacks on Saudi Arabia's Abha International Airport mark a significant escalation in hostilities, following a truce that was reached in 2022. The Houthis are a key part of Iran's 'Axis of Resistance,' which includes various militant groups across the Middle East. The rebels have a stockpile of drones, but reports indicate that their resources are dwindling due to the ongoing conflict and restrictions on weapon flows. The U.S. and Israel have previously responded to Houthi attacks on shipping with air campaigns targeting Houthi positions in Yemen, but a temporary deal had been reached to halt these assaults. The current maritime embargo could force shipping companies to reroute vessels around the Cape of Good Hope, significantly increasing transportation costs and impacting global trade.
