Houthi Advance Threatens Bab al-Mandeb Strait and Sparks Massive Displacement
By Drooid · · How we work
Core Event
- On September 10 Houthi fighters seized Mocha, followed by Dhubab and Perim on September 11, gaining control of the Bab al-Mandeb Strait, the Red Sea-Gulf of Aden chokepoint.
Background & Context
- The Iran-aligned Houthis, who have held Sanaa since 2014, stepped up after the July 20 naval blockade declaration against Saudi Arabia. The 2022 UN truce held until a July flare-up when government forces hit a Houthi-held airport, prompting the current offensive. Iranian Revolutionary Guard officers are reported to have provided guidance and weapons.
Data & Statistics
- Refugee flow: 1,400 Yemenis arrived in Obock, Djibouti within 24 hours, per Djibouti’s minister of economy Ilyas Moussa Dawaleh.
- Displacement: IOM figures range from 46,000 displaced since the recent fighting to 76,000 since July.
- Shipping: On September 9, seven vessels crossed the Strait of Hormuz versus 28 transiting Bab al-Mandeb.
- Oil flow: Saudi crude exports via the Red Sea fell to about 2.2 million bpd in August, down from 3.8 million bpd earlier in the month.
Impact
- Control of Bab al-Mandeb affects roughly 12 % of global trade and 7 % of world oil shipments. Rerouting around the Cape of Good Hope adds weeks and millions of dollars to costs. Humanitarian conditions worsen as families flee with “almost nothing left.”
Official Statements & Responses
- IOM director-general Amy Pope warned families are forced to flee repeatedly and called for safe humanitarian access.
- Djibouti’s minister Ilyas Moussa Dawaleh posted that 1,400 refugees arrived in Djibouti in 24 hours.
- Saudi coalition spokesperson Maj. Gen. Turki al-Maliki said the Houthis were “persisting” in attacks and pledged a response.
On-the-Ground Reports
- IOM’s Safiya Ibrahim noted women and children reaching Obock’s shores, with more expected. Mocha residents described an “apocalyptic” atmosphere, shuttered markets and closed roads.
Conflicting Reports & Gaps
- Displacement figures differ (46,000 vs 76,000) due to different reporting windows.
- Vessel traffic data show a sharp decline in Hormuz crossings but only a modest dip in Bab al-Mandeb movements, leaving uncertainty about the immediate shipping impact.
