Up to 169 killed in 3 days over Yemen's Kahbub heights; casualty figures from the parties and the WHO do not match
Up to 169 deaths have been reported since 20 September as the Houthis and Saudi-backed government forces fight for the Kahbub mountains overlooking Bab el-Mandeb. Houthi sources give 118 dead, government sources 36; the WHO counts 674 deaths since 6 August, while displacement figures range from 82,000 to 158,000.
According to the Guardian, the Kahbub mountains between Taiz and Lahj provinces became the main front after the Houthis seized the Red Sea coast, including the port of Mocha, in early September. As reported by Red Sea Brief, the Giants Brigades, National Shield forces and Subaiha tribal fighters retook the heights on 18 September; Yemen Monitor wrote that hundreds of Houthis had been killed or wounded, but this figure has not been verified. On 19 September the government said a Houthi field commander and 6 aides had been killed; the Houthis did not confirm this. As reported by Al Jazeera, 118 Houthi fighters and 36 government soldiers have been killed since 20 September in fighting and air strikes in Taiz, Al-Jawf, Marib, Saada and Lahj. The Guardian adds 6 civilians in Mocha and 9 detainees killed in an attack on a prison in Al-Jawf, taking the 3-day total to as many as 169.
On civilian casualties, the only source is the Houthi side. According to the Houthi-run Al-Masirah television, Saudi aircraft carried out at least 157 air strikes in Al-Jawf, Taiz, Saada and Marib on 21 September; 3 strikes on a house in Mocha killed 6 people, including 2 children, and wounded 8. Saudi Arabia did not respond to these claims, and the figures could not be independently verified.
The overall toll also diverges. The World Health Organization recorded 674 deaths and about 3,000 wounded since 6 August, and 164 deaths and 516 wounded between 13 and 18 September alone; the Guardian speaks of about 700 deaths since the start of the offensive. On displacement, the Yemeni government's camps unit counted more than 158,000 people, or about 23,550 families, this month, while the Guardian gives a figure above 100,000 and the International Organization for Migration's mid-September data above 82,000.
Talay assessment
Bottom line
The Kahbub heights are the last high ground overlooking the Bab el-Mandeb coastline and Mayun island seized by the Houthis; that is why both sides are willing to take heavy losses. Up to 169 deaths in 3 days and the claim of 157 air strikes show Saudi air power trying to offset losses on the ground. None of the figures has been independently verified; the most likely path is for the front to lock up around the heights for weeks.
Likely effects
- Red Sea shippingNegative1–6 months
Who holds the heights determines whether transits through Bab el-Mandeb remain within artillery and drone range; this directly affects freight and war-risk insurance.
- Humanitarian situationNegativeWeeks
The WHO's record of 674 deaths since 6 August and displacement of up to 158,000 are narrowing aid access and could increase crossings to Djibouti.
- Turkish maritime tradeNegative1–6 months
Continued risk on the Red Sea route keeps delivery times and freight costs high for Turkish exporters and importers trading with Asia.
Possibilities, ranked
- 1Deadlock around the heights55%
The parties keep up mutual attacks around Kahbub, and neither side gains decisive control of the coastline.
Watch: The WHO's weekly casualty bulletin and the daily air strike counts reported by Houthi-run Masirah TV
- 2Houthis retake the heights30%
The Houthis retake Kahbub, consolidating their control of the Bab el-Mandeb coastline, and government forces pull back towards Aden.
Watch: Confirmation of a change of control at Kahbub from Yemen Monitor and Houthi sources
- 3Ceasefire through mediation15%
Under pressure from the G7 and regional mediators, a temporary ceasefire is declared on the coastal front.
Watch: Simultaneous ceasefire statements from Saudi Arabia and the Houthis
