NEW: The Houthis have, at least for now, prevented further Yemeni government advances northward on the Red Sea coastal plain. ISW-CTP is adjusting its previous assessment that Houthi forces on the coastal plain are collapsing in light of evidence in the last 24 hours indicating that the Houthis have stopped Yemeni government-aligned advances.

Other Key Takeaways:

A temporary pause in the Yemeni government ground advance provides both the Houthis and the Yemeni government with time to consolidate their combat forces and positions. The Houthis may use the current pause in government advances on the coastal plain to deploy more reinforcements to the operational area and strengthen defensive positions north of the frontline.

A successful Yemeni government counteroffensive in the mountains east of the coastal plain could support Yemeni government-aligned forces’ advances northward on the coastal plain.

Saudi naval and air forces targeted Houthi military and maritime assets on October 5 that the group could use to attack shipping in the Bab al Mandeb Strait, amid the broader Saudi and Yemeni air campaign to degrade Houthi strike capabilities and support Yemeni government-aligned forces.

The Houthis significantly expanded the scale of their attacks on Saudi military and civilian infrastructure on October 5, likely to compel Saudi Arabia to abandon its support for ongoing Yemeni government counteroffensives. The Houthis believe that they can maximize Saudi economic costs and compel Saudi Arabia to surrender to Houthi demands by striking civilian infrastructure, such as oil facilities and airports.

Houthis are claiming that Abdulrahman al-Shamsani, commander of the 35th Armored Brigade, was killed during the fighting at Jabal Matran. They are also claiming that they seized weapons and secured the mountain.

Yemen’s government has denied both claims. The 35th Armored Brigade says al-Shamsani is alive and personally leading the fighting in the area, while government sources say clashes around Jabal Matran are still ongoing.

If the Houthis are able to hold Matran and push farther into Bani Yusuf, this becomes much more significant. It would strengthen their position on the southern approaches to Taiz and increase pressure on the corridor toward Aden. This is becoming an increasingly important focus for the Houthis in their military strategy; Iranian media has also been advertising wins freely before the Houthis even set foot there, so this is an important focus for IRGC.

MORE: Government-aligned forces are already at Dhubab Airport, which is 54km from Mokha, and some local media have published uncorroborated footage of government-aligned forces entering Mokha after reported Houthi withdrawals. ⬇️

The retreat of Houthi lines at Mayyun (Perim) Peninsula northwards to at least Dhubab (a distance of approximately 30 km) suggests a major collapse, and there is no evidence currently that the Houthis have halted the collapse of their forces.

This collapse indicates that Yemeni government forces will be able to push the routed Houthis further north rapidly, possibly to and beyond Mokha if conditions hold. Indications that the Houthis have successfully brought the collapse under control south of Mokha would include sustained fighting in the same locations over some period along the coast.

ISW-CTP will continue to watch for indications that the Houthis have reestablished defensive positions. Local Yemeni media posted unverified footage reportedly showing Houthi fighters leaving Houthi-held positions north and east of Mokha city on October 5, suggesting that the collapse is ongoing and that the Houthis have not reestablished defensive positions after the initial collapse
