Iran Threatens Bab al-Mandeb Strait as Tensions Escalate
Tehran is warning it could target the Bab al-Mandeb Strait, a critical global shipping route, if the United States and Israel escalate military actions, particularly with any ground invasion of Iranian territory. This threat adds to existing concerns about the Strait of Hormuz, through which approximately one-fifth of the world’s oil flows, potentially creating a significant disruption to global trade and energy markets.
Strategic Importance of Bab al-Mandeb
The Bab al-Mandeb Strait, meaning “Gate of Tears” in Arabic, links the Red Sea with the Gulf of Aden. It is one of the world’s most significant maritime corridors, handling a substantial share of global shipping and oil flows. Interference with traffic through this strait would have far-reaching economic consequences, exacerbating existing disruptions already seen in the region [1].
Iran’s Warning and Potential Actions
According to sources within Iran’s Islamic Revolutionary Guard Corps (IRGC), if the U.S. Or Israel take action on Iranian land or naval movements in the Persian Gulf and the Sea of Oman, Iran will “open another front” as a surprise [1]. This suggests potential attacks targeting shipping in the Bab al-Mandeb Strait using shore-based missiles, drones, and small-boat attacks [2].
The Strait’s Geography and Vulnerabilities
The Bab al-Mandeb Strait is a 29-kilometer-wide passage between Yemen and Djibouti/Eritrea. It is divided into two channels by Mayyun Island: a narrower eastern channel for smaller vessels and a wider western channel used by most large commercial traffic [2]. Ships gradual down and funnel into predictable lanes, making them vulnerable to attacks from the Yemeni coastline [2].
Connection to the Strait of Hormuz
While geographically distant (between 3,500km and 4,000km by sea), the Strait of Hormuz and Bab al-Mandeb are operationally linked. Ships traveling from the Gulf exit via Hormuz, cross the Arabian Sea, enter the Gulf of Aden, pass through Bab al-Mandeb, and then proceed into the Red Sea towards the Suez Canal and onward to Europe and other markets [2]. Compromising both straits would severely impact supply chains, energy markets, and shipping costs globally.
Economic Impact of a Blockade
Approximately $1 trillion in goods transit the Bab al-Mandeb Strait annually [1]. A blockade would disrupt this vital trade route, leading to increased shipping costs, delays, and potential shortages of goods. The combined impact of disruptions at both the Strait of Hormuz and Bab al-Mandeb could be substantial.
Iran’s Broader Strategy
Iran’s threats regarding Bab al-Mandeb are seen as part of a broader strategy to deter the U.S. And Israel and to increase its leverage in the region. By threatening two critical chokepoints simultaneously, Iran aims to raise the stakes and discourage military intervention [2].
