Three days of sustained attacks on Israel establish that Ansar Allah can maintain tempo. The question is whether they close the strait.

Key takeaway

The Houthi front is calibrated escalation, not symbolic gestures.

Ansar Allah struck Israel for a third consecutive day on 30 March . All projectiles were intercepted. Deputy Information Minister Mohammed Mansour described Bab al-Mandeb closure as "among our options" in a staged escalation, contingent on Israeli or US ground movement. ¹

No formal blockade has been imposed. All vessels, including US- and Israeli-linked ships, continue to transit. But three days of attacks confirm sustainable operational tempo. Combined with near-total Hormuz closure, a formal Bab al-Mandeb blockade would place simultaneous pressure on the world's two most critical oil transit routes for the first time since the 1973 oil crisis. MARAD and UKMTO have already confirmed deliberate GNSS denial spanning both chokepoints .

Deep Analysis

In plain English

The Houthis control much of northern Yemen and have been attacking ships in the Red Sea since 2024. They are also allied with Iran. For three days running, they have fired missiles and drones toward Israel; all were intercepted. Bab al-Mandeb is a narrow strait between Yemen and Djibouti. About 10% of all world trade and a large share of oil from the Gulf to Europe passes through it. If the Houthis block it, combined with Iran blocking the Strait of Hormuz, two of the world's main oil routes would be shut simultaneously. That last happened in 1973 during the Arab oil embargo. It triggered a global recession. The Houthis have not closed Bab al-Mandeb yet, but their deputy minister said it is an option.

This Event

Houthis threaten second chokepoint

A formal Bab al-Mandeb blockade combined with Hormuz closure would simultaneously shut the world's two most critical oil transit routes for the first time since 1973.

Different Perspectives

Hengaw

The Norway-based monitoring group reported the Urmia executions of Omid Behzad and Pouria Safvat, the only source to do so, consistent with its documented pattern of recording far more executions than the Iranian state acknowledges. Iran's government has not confirmed either execution.

Shipping and insurance underwriters

War-risk premiums price the Houthi campaign because the group announces its targets in advance, but a reopening Trump has promised without a published text gives underwriters no benchmark to reprice Hormuz cover against. Insurers want a text before they move rates, not a promise.

Houthi movement

Spokesman Yahya Saree claimed strikes on two tankers in the Red Sea and Gulf of Aden on 5 August, only one of which UKMTO could confirm. The group's campaign against shipping continues on its own schedule, independent of any Hormuz arrangement further north.

Oman

Muscat has brokered the coordinates both Tehran and Washington's wire sources now describe differently, but has published no account of its own. Oman's position depends on treating Hormuz as a shared route, which is not what Iran is currently describing.

United States Central Command

CENTCOM raised its interdiction tally from 35 to 44 redirected vessels and disclosed its first boardings on 3 August, the day before Trump promised a reopening. The command's own enforcement record does not yet reflect the release the President has described.

Iran's Foreign Ministry

Spokesman Esmaeil Baghaei described the agreed Hormuz coordinates as a wholly new corridor under Iranian management, not a split of the existing route, days after his own deputy rejected Oman's lane proposal. Tehran wants the arrangement read as a change of ownership, not a compromise on access.
