The Bab el-Mandeb Strait, a critical maritime artery connecting the Red Sea to the Gulf of Aden and the Arabian Sea, is facing escalating threats from Houthi attacks, prompting comparisons to the Strait of Hormuz and raising concerns about global shipping and energy security.
The waterway, situated between Yemen and the Horn of Africa, is vital for commercial and energy shipments en route to the Suez Canal and the Mediterranean. However, its security is complicated by the fractured political and military landscape within Yemen, where Iran-backed Houthi forces control significant territory, including the capital Sanaa.
Recent incidents have underscored the growing danger. On Tuesday, the Houthi group attacked the Egyptian-owned cargo ship Tihamah in the Bab el-Mandeb, resulting in the deaths of four crew members. A subsequent strike as rescue crews arrived killed two Yemeni rescuers, according to Yemeni and Pakistani officials. These fatalities, if confirmed, would mark the first deaths from a Houthi strike on shipping since February 28.
Amr Al Bidh, the Southern Transitional Council's foreign affairs chief, stated that naval patrols can protect individual vessels but cannot eliminate the threat posed by Houthi launch sites or interdict supply routes. He emphasized the need for a ground presence to secure the strait effectively.
The situation in Bab el-Mandeb is unfolding amid a broader escalation in Yemen. U.N. Special Envoy Hans Grundberg has warned of the most serious threat of a return to large-scale war since a 2022 truce, noting that Houthi attacks on commercial vessels risk drawing Yemen deeper into regional confrontations.
In July, the Houthis declared a naval blockade of Saudi Arabia, threatening vessels conducting business with Saudi ports. While Riyadh denies accusations of a siege, the U.S. has stated its expectation that the Houthis will uphold ceasefire terms. A White House official noted that the U.S. and President Trump are prepared to take necessary actions to protect freedom of navigation and U.S. commercial shipping from Houthi attacks.
United Against Nuclear Iran reported a roughly 40% decline in tanker transits since the July 20 blockade declaration, with tankers observed broadcasting messages indicating their ownership and the presence of armed guards to deter targeting.
China has reportedly engaged with the Houthis to ensure safe passage for its vessels. Following the blockade announcement, four China-bound tankers transited Bab el-Mandeb after Beijing sought assurances.
The strategic importance of the Red Sea corridor has increased as shipping through the Strait of Hormuz faces disruptions due to the U.S.-Iran conflict. This makes the Red Sea both an alternative route and a potential secondary pressure point.
Yemeni Nobel Peace Prize laureate Tawakkol Karman has cautioned that Yemen's internal instability threatens international interests, including navigation, trade, energy security, and global supply chains. She advocates for restoring a functioning Yemeni state as essential to defeating armed groups and securing the country.
However, U.S. experts caution against viewing Bab el-Mandeb as a direct parallel to Hormuz. Richard Goldberg, a senior adviser at the Foundation for Defense of Democracies, noted that Iran's direct influence over Bab el-Mandeb is less pronounced than over Hormuz, with Houthi actions being more independent. He also pointed out that unlike Hormuz, ships unable to transit Bab el-Mandeb can reroute around Africa, albeit with increased cost and time.
In response to the growing threat, Saudi Arabia is pursuing a two-pronged approach to regional maritime security. On August 7, Saudi Arabia, Turkey, and Pakistan signed the Mecca Joint Defense Agreement, a mutual defense pact that includes political and military coordination, joint exercises, and defense industry cooperation. While Turkey has emphasized its defensive nature, the agreement could lead to increased coordination against Iran-backed groups like the Houthis.
Separately, Saudi Arabia is leading an initiative to establish a multinational maritime-defense coalition. Announced on July 30, the coalition aims to protect freedom of navigation and commercial routes through Bab el-Mandeb, the Red Sea, and the Gulf of Aden. Initial backing has come from fourteen countries, including Turkey, Pakistan, Egypt, Sudan, and Djibouti.
A State Department spokesperson affirmed that protecting commercial shipping through the Red Sea and the Strait of Hormuz remains a top priority for the Trump administration, emphasizing freedom of navigation as a core U.S. national security interest. The U.S. is working with international partners to deter attacks and disrupt the flow of Iranian weapons and funding to the Houthis, having sanctioned over 200 entities associated with the group. The U.S. also condemned Iran's actions and reiterated its support for Saudi Arabia and Yemen's internationally recognized government.
