5/ There no basis to assess that Russian forces will be able to take the rest of Donetsk Oblast in any short period of time, as Russian President Vladimir Putin continues to claim, or even to forecast that Russian forces will ever be able to complete their seizure of this region by force.

6/ A parliamentarian from Iranian-backed Iraqi militia Asaib Ahl al Haq’s (AAH) political wing appeared to downplay the gravity of Zaydi’s reported amendments to the PMF law, which could reflect AAH support for some of Zaydi’s PMF efforts. Read the full report: isw.pub/IranUpdate10...

5/ Multiple Shia Coordination Framework members are fighting Zaydi’s attempts to meet US demands about militias. Iraqi media reported that Zaydi and unidentified framework members disagree on many amendments to the draft PMF law, despite Zaydi’s office claiming the govt sent the bill to Parliament.

4/ Zaydi is trying to assuage US concerns over Iranian-backed Iraqi militias by amending draft legislation to balance between Iran and its Iraqi allies and the US. Qatari-funded, UK-based media reported that Zaydi-affiliated Iraqi federal government officials have drafted amendments to the PMF law.

3/ The Houthis targeted reported Saudi and international efforts to supply the Yemeni government with materiel to sustain the government’s operations against the Houthis. The Houthi strike on Aden Airport comes amid a recent increase in the scale of Houthi strikes on Saudi Arabia since October 5.

2/ More Key Takeaways The Yemeni govt & partners didn't set sufficient political conditions before initiating recent counteroffensives, hindering their effectiveness. The recent, sudden collapse of Yemeni govt-aligned forces along the frontline in Taiz Governorate indicates a lack of coordination.

Iran Update, October 7, 2026: Houthi advances in Taiz Governorate demonstrate that the Yemeni government’s recent counteroffensives failed to sufficiently pull Houthi reserves to relieve pressure around Taiz and enable Yemeni government offensive operations in other areas of the country. (1/6)

7/ 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.

Institute for the Study of War @thestudyofwar.bsky.social · 07/10/2026
6/ 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.

Institute for the Study of War @thestudyofwar.bsky.social · 07/10/2026
5/ 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.

Institute for the Study of War @thestudyofwar.bsky.social · 07/10/2026
4/ 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.
1290
Institute for the Study of War @thestudyofwar.bsky.social · 07/10/2026
3/ 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.

2/ 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.

9/ Iran is likely aiming to increase its ability to deter US airstrikes targeting Iranian assets, impose costs on the United States, and preserve strategic initiative in the conflict by prioritizing improvements to its missile capabilities.
1413
Institute for the Study of War @thestudyofwar.bsky.social · 06/10/2026
8/ Iran is likely reconstituting and enhancing its ability to target distant US regional military targets and commercial shipping through improvements in missile accuracy, range, speed, and targeting capabilities.

Institute for the Study of War @thestudyofwar.bsky.social · 06/10/2026
7/ The Iranian regime appears increasingly concerned that mounting economic pressure could threaten internal stability and is combining its attempts to manage its wartime economy with expanded efforts to deter and prepare to suppress possible unrest.

6/ Saudi allies in the Mecca Pact are providing military aid to Saudi Arabia, and Saudi Arabia announced on October 5 that Pakistan and Turkey are taking “practical measures” to defend Saudi Arabia pursuant to the Mecca Pact requirements.

Institute for the Study of War @thestudyofwar.bsky.social · 06/10/2026
5/ Allied air and intelligence support almost certainly made this offensive possible. Over 100 Saudi aircraft provided air support to Yemeni government-aligned forces during the initial assault, and US intelligence is reportedly supporting the air campaign.
1320
Institute for the Study of War @thestudyofwar.bsky.social · 06/10/2026
4/ The Yemeni government will need to secure its own defensible line before its offensive culminates in order to ensure it can repel Houthi attacks combining drones and ground forces, which the Houthis employed in early September.
1320
Institute for the Study of War @thestudyofwar.bsky.social · 06/10/2026
3/ Yemeni government-aligned forces will likely stop offensive operations within the next seven to 14 days to rest, resupply, and consolidate their positions to prevent a Houthi counteroffensive.
1320
Institute for the Study of War @thestudyofwar.bsky.social · 06/10/2026
2/ Other Key Takeaways: This offensive will likely succeed in capturing Mokha in the short term. Saudi Arabia and the Yemeni government likely launched the offensive to accomplish the limited objective of securing the Bab al Mandeb.

3/ Russia has successfully used jet-powered drones to degrade Ukraine’s railway infrastructure and rolling stock.
1482
Institute for the Study of War @thestudyofwar.bsky.social · 05/10/2026
