On 3 September 2026, the Iran-backed Houthis launched an offensive against the Saudi-backed Presidential Leadership Council (PLC), the internationally recognized government of Yemen, amid the ongoing Yemeni civil war. Clashes began in Taiz Governorate, prompting a PLC counter-offensive against the Houthis in the Al-Jawf and Al-Bayda governorates.
The fighting coincides with the ongoing 2026 Iran war, which has marked the deadliest fighting in Yemen since the collapse of the 2022 ceasefire. The Yemeni government lost areas around the Bab al-Mandab Strait in Yemen's southwest after a swift battle over Mokha, resulting in a crisis with the entire west coast of Yemen (except for the Midi district) falling under control of the Houthi movement, who named the operation as Operation Allah is Stronger in Might and More Severe in Punishment. The counteroffensive of the PLC against the Houthis was named Operation Dawn of Yemen.
Background
2022 ceasefire and the Red Sea crisis
The Houthis and the internationally recognized government of Yemen reached a ceasefire agreement in 2022, which largely held until the 2026 campaign. Peace talks stalled in 2023 amidst the Gaza war. Starting on 19 October 2023, the Houthis began launching missiles and drones at international shipping crossing the Bab al-Mandab Strait in solidarity with Palestinians during the war in Gaza, triggering the Red Sea crisis. In response, a US-led multinational coalition launched Operation Prosperity Guardian in late 2023 to secure shipping through the Red Sea. In early 2024, the United States and the United Kingdom launched a series of airstrikes targeting Houthi missile and drone launch sites across Yemen. In March 2025, the United States launched a larger wave of strikes against the Houthis, after which the Houthis agreed to stop attacking U.S. vessels in the Red Sea. Additionally, Israel previously launched a series of airstrikes on Houthi-controlled Yemen in response to missile attacks by the group, including a July 2024 strike on Tel Aviv that killed one person. Following the implementation of the Gaza peace plan in 2025, both parties briefly ceased attacks until March 2026, when the Houthis again launched missiles toward Israel in support of Iran and the Axis of Resistance, all of which were intercepted.
2026 Iran war and escalation
On 28 February 2026, the United States and Israel launched a large-scale attack on Iran, aimed at regime change. Iran and its allied militias, including Hezbollah and the Iraqi Popular Mobilization Forces, retaliated against U.S., Israeli, and other regional countries' military and energy infrastructure with drone and missile strikes. The Houthis initially refrained from joining the fighting, breaking with the rest of the Axis of Resistance, only joining the war on 28 March.
When the US navy reimposed its naval blockade against Iran on 14 July 2026, the Islamic Revolutionary Guard Corps (IRGC) of Iran threatened to cut "all other export corridors that benefit the US and its allies", with a senior Houthi official warning that the group was prepared to close the Bab al-Mandab Strait. On 16 July 2026, Reuters reported that Iran had asked the Houthis to be ready to close the strait should the US strike Iranian power infrastructure. Soon after the Houthis began deploying drones and missiles near the Bab al-Mandeb Strait.
On 13 July 2026, a Mahan Air flight carrying IRGC commanders and weapons attempted to land at Sanaa Airport, in the Houthi-controlled capital. Yemeni government forces and Saudi Arabia responded by striking the airport's runway to prevent the landing. In retaliation for the strike, the Houthis declared the ceasefire with the Yemeni government and Saudi Arabia over. On 20 July, the Houthis announced a naval blockade on Saudi Arabia, amid the renewed U.S. naval blockade of Iran. The Houthis subsequently began striking Saudi oil tankers in the Red Sea. On 24 July, Saudi Arabia retaliated against the earlier Houthi strikes on its oil tankers by bombing Houthi targets in the port city of Hodeidah. In response, the Houthis struck the Jizan oil refinery and the port city of Yanbu in Saudi Arabia two days later. Starting on 6 August, the Houthis also started striking Yemeni government forces across the country with missiles and drones, killing and injuring dozens of troops.
Timeline
3–9 September
On 3 September, the Houthis launched what was described as a "massive offensive" in the Taiz Governorate, attempting to cut the road linking Taiz to Mokha and thus sever Taiz city from the coast and escalate the Siege of Taiz. At least 129 people were reportedly killed (At least 66 Yemeni Government / PLC soldiers, At least 62 Houthi Militia Forces fighters, and At least 1 Yemeni civilian) in the clashes.

Following their withdrawal from Mokha district, the PLC declared a "kill box" around the area, intending to use "all weapons and firepower", and warning civilians to avoid the Taiz–Mokha road until further notice.
Following the incident that occurred between the Southern Resistance and the PLC the day prior, Southern Resistance's Brigadier General Ali Shaif Al-Hariri, an official spokesperson of the group, issued a formal statement categorically rejecting and condemning the disruption of Minister Al-Aqili's convoy. Al-Hariri labeled the ambush a "reprehensible and unacceptable act" that ran counter to the tribal customs and history of Dhale. The official leadership statement emphasized that internal political differences within the resistance must not escalate into violence or chaos, stating that his group should focus most of its firepower against the Houthis instead. On the same day, the General Union of Southern Arabian Tribes stated its support for the events that took place in Dhale and stated it was ready to support the Southern Resistance with men and equipment, following up with an official call to arms the following day.
On 11 September, the Houthis claimed control over Yemen's entire Red Sea coast, including the Perim Island and the al-Omari camp.

Reports of the Houthis taking Perim islands were also confirmed by Saudi and PLC sources.
Axios reported that Saudi Crown Prince Mohammed bin Salman called President Donald Trump twice on 10 September, urging him to launch strikes against the Houthis, but that Trump rejected the request.

Saudi airstrikes targeted the Mokha airport.
