They took Mayun. The mouth of the strait.

Photograph: anonymous / Rijksmuseum RP-F-F16253-A. Public domain / CC0. The geography of this product is the reported Houthi seizure of Mayun Island at the mouth of Bab al-Mandeb — not the Mocha city advance, not the Saudi-city strike wave, not a Hormuz tanker round.
Al Jazeera reported on 12 September 2026 that Iran-aligned Houthi forces seized Mayun Island — also known as Perim — at the mouth of the Bab al-Mandeb. The piece attributes confirmation to an official of Yemen’s internationally recognized government and to a Houthi official. The island sits in the strait that links the Red Sea to the Gulf of Aden; the same reporting ties the seizure to the earlier reported capture of Mocha (Mokha) and to Houthi control claims along Yemen’s Red Sea coast.
Independent coverage from NPR, Dallas Morning News, and other outlets had already described the Houthi coastal advance and the shipping risk at Bab al-Mandeb. What this reporting adds is explicit dual confirmation of the island seizure itself, not the first notice that Houthis were moving on the Red Sea approaches.
## Why it matters
Mocha is a port city on the coast. Mayun is an island in the strait. Control of the island, if durable, is a different military geography: shorter missile and observation ranges over traffic that already faces war-risk pricing after prior Red Sea disruptions. Fortune and other outlets the same day framed Saudi Arabia as facing pressure on two export corridors at once — the East-West pipeline inland and Red Sea shipping after the coastal advance — which is a dual-chokepoint reading, not a Mocha-only story.
The Mocha product is the port-city advance. This page is the island claim.
## What is reported
- Al Jazeera (12 Sep): Mayun/Perim seized; confirmation attributed to a Yemeni government official and a Houthi official; holdability of the island treated as an open military question.
- Same-window corroboration: multiply reported advance and seizure language across outlet families; no supplied primary battlefield imagery package on the open record used here.
- Fortune, same day: East-West pipeline closure after drone attacks attributed to Iraq-based militias, paired with Mocha/island coastal pressure — dual-corridor frame.
## Inference (not a finding)
The most plausible near-term read is expanded Houthi leverage over Bab al-Mandeb approaches, contingent on whether Saudi-backed Yemeni forces contest the island and whether restrictions stay limited to Saudi-linked traffic or widen. Shipping disruption can appear before any formal blockade — through insurance, charter rates, and voluntary Cape diversions — even if most commercial traffic is still allowed through.
## Uncertainty
- Durability of physical occupation versus a brief raid, contested presence, or overstated claim is not settled by the available reporting.
- No UKMTO, carrier, or insurer product naming Bab al-Mandeb specifically because of Perim appeared on the same-day open record.
- Primary battlefield verification (imagery or on-island naval/Yemeni documentation beyond attributed officials) remains thin on that record.
## What happens next
- Whether Saudi-backed Yemeni forces announce or attempt a contest of Mayun or the adjacent coastal approaches.
- Whether Houthi statements or maritime advisories expand restrictions beyond Saudi-linked vessels.
- Whether war-risk quotes, charter rates, or reported vessel diversions around the Cape show the island claim becoming an operational shipping product — not only a geography claim.
## Distinct from
- bab-mandeb-mocha (Mocha/Mokha city and Bab second-order question).
- saudi-houthi-cities (Saudi-city kinetic / wounded count).
- hormuz-kharg-tankers and hormuz-five-tankers (Gulf / Hormuz kinetic).
