Houthi missile and drone salvos on Marib and Hadramawt, a Yemeni army counter-operation across multiple fronts, and a maritime campaign that has emptied Bab al-Mandeb have left the UN warning of the highest escalation risk since the April 2022 truce
Yemen's internationally recognised army announced on Saturday that it had struck Houthi positions along several fronts, closing a seventy-two-hour cycle of violence that has effectively dismantled the de facto truce which has held inside the country since April 2022.
The announcement, carried by the Defence Ministry and attributed to army spokesman Col. Majid al-Nuzaili, was framed as retaliation for missile and drone attacks on military camps in the governorates of Marib and Hadramawt. The army gave no operational detail and did not say when the strikes took place. It said it would meet any further targeting of its units with what it called necessary military measures, and warned that it would respond without hesitation if the attacks continued.
That statement followed two days that Yemeni analysts and United Nations officials alike describe as a turning point. UN Special Envoy Hans Grundberg, in a statement issued from Amman on Friday, said Yemen now faces a greater risk of renewed large-scale conflict than at any point since the UN-brokered truce of April 2022. The Security Council issued its own expression of concern the same day, urging the Houthis to refrain from escalation and pointing to threats against regional security and navigational freedoms.
Three Days that Ended the "Neither War nor Peace" Equilibrium
The sequence began on Thursday, 6 August. Yemeni government sources said Houthi forces fired eight missiles from al-Jawf governorate, north of Marib, striking al-Thiniya and al-Abr in Hadramawt and al-Rouk in Marib. The salvo landed on camps belonging to the Homeland Shield Forces, the Emergency Forces and the First Military Region. Casualties were unusually heavy because troops had assembled for a morning training exercise, according to the First Emergency Division Command.
The choice of targets is analytically significant. Both formations struck are products of Saudi force-building rather than legacy units of the Yemeni army. The Homeland Shield Forces were raised in 2022 with Saudi backing, number in the tens of thousands, and hold the Marib–Hadramawt frontier and the approaches to the Saudi border. The Emergency Forces were created by presidential decree in late 2025 under Saudi-led coalition supervision to secure the land borders and the anti-Houthi fronts in al-Jawf and Hadramawt. Sanaa was not striking the Yemeni state in the abstract; it was striking the order of battle Riyadh has assembled since the truce.
Houthi military spokesman Yahya Saree said the operation was launched after his forces detected a large Saudi military buildup preparing an escalation against areas under their control. The movement also declared what amounts to a new rule of engagement: any Saudi movement toward Yemeni territory, or in the reverse direction, would be targeted immediately.
Hours later, the Saudi-led coalition reported that a Houthi attack on the southern province of Najran had wounded eleven people — seven Saudis, one Yemeni, two Egyptians and a Pakistani national, among them a four-year-old child with second-degree burns. Coalition spokesman Maj. Gen. Turki al-Maliki accused the group of indiscriminate shelling of civilian areas. The Gulf Cooperation Council's secretary-general, Jasem Mohamed Albudaiwi, condemned the strikes in the strongest terms and voiced support for whatever measures Riyadh takes to protect its territory.
On Friday, 7 August, the tempo increased rather than subsided. Al Jazeera's correspondent in Sanaa reported at least twelve further missile attacks on Hadramawt and Marib since the early hours. Yemen's state television said air defences had brought down a number of Houthi drones over Marib. The Houthis said they had struck Saudi-backed forces, depots, vehicles and equipment at the Sahn al-Jinn camp.
The day's most consequential attack, politically, was the one that fell on Marib city itself. The state news agency SABA, citing local authorities, reported that ballistic missiles and drones hit displacement camps and residential neighbourhoods, killing two people and wounding fourteen. Marib hosts the largest displaced population in Yemen. The Ministry of Public Health and Population condemned the strike and said health facilities had been ordered to raise their alert levels. Separate accounts from a Yemeni military source and the health minister put Friday's overall toll in the governorate at roughly ten dead, including government troops killed in a drone strike and civilians killed by shelling.
A Contested Casualty Ledger
Any reporting on the past three days must carry a clear caveat: the numbers do not reconcile, and neither side's claims have been independently verified.
For Thursday's strikes alone, government sources briefed a toll of at least 30 soldiers killed and 15 wounded, with the figure expected to rise. Yemen's Defence Ministry announced 17 soldiers and officers killed. Medical sources cited by Anadolu put the number at 38. Ansar Allah initially claimed 45 dead, then raised the figure to 58, while Saree told a televised audience that the attacks had killed "hundreds" and destroyed a large number of camps and depots.
Reuters, reporting from Cairo and Aden, stated plainly that it could not verify the claims of either side. The same caution applies to the maritime campaign, where Saudi authorities have confirmed almost none of the vessel strikes the Houthis have announced.
The Maritime Front: From Harassment to Blockade
The land escalation is inseparable from what has happened at sea since 20 July, when the Houthis declared a naval blockade of Saudi Arabia in response to what they called a Saudi siege of Yemen — an allegation Riyadh rejects.
The declaration followed the 13 July strike on the runway at Sanaa International Airport, carried out to prevent an Iranian aircraft from landing. The internationally recognised government claimed responsibility, saying the aircraft was arriving without authorisation; Yemen's ambassador to the UN, Abdullah al-Saadi, told the Security Council this week that the plane was linked to the Islamic Revolutionary Guard Corps and carried personnel, expertise and military and dual-use equipment. The Houthis blamed Riyadh and announced that the de-escalation phase of the war was over.
Since then the group has claimed strikes on the tankers Encelia and Layla on 22 July, on Aramco facilities at Jizan and Yanbu on 26 July after Saudi airstrikes on Hodeidah, on the NCC Ghazal, on the Wafa off Yanbu in the northern Red Sea, and on the Daisy in the Gulf of Aden on 5 August. The group frames all of this through what it calls the "siege for siege" equation, and says Saudi tankers will not be permitted through either the southern Red Sea or the northern approaches until the blockade on Yemen is lifted.
The commercial effect has been immediate. Reuters shipping data showed transits through Bab al-Mandeb collapsing to a single vessel from around twenty in preceding days, with heavy GPS spoofing across the region. Brent crude climbed to $83.34 a barrel by 06:34 GMT on Friday after settling above $82 on Thursday.
The strategic stakes are larger than tanker insurance. With the Strait of Hormuz largely closed since the US–Israeli war on Iran began on 28 February, Saudi Arabia has been routing millions of barrels per day through its East–West pipeline to Yanbu on the Red Sea. Bab al-Mandeb is the outlet for that alternative corridor. Yemen's foreign minister-designate, Afrah al-Zouba, has argued that the Houthis are seeking to replicate Iran's Hormuz model, closing the gateways to both the Gulf and the Red Sea. Riyadh responded in late July by convening a new international coalition to protect Red Sea shipping; thirteen states had agreed to join as of 30 July.
The Regional Overlay
Three external developments frame the Yemeni escalation.
First, intelligence warnings. A senior Saudi official told Reuters on Friday that Saudi, American and other regional services expect imminent coordinated attacks by the Houthis and Iraqi armed groups under IRGC supervision, potentially against energy infrastructure, ports and airports. Iran and its allies have not responded to the claim. The official added that Saudi–US cooperation, including with Central Command, remains close.
Second, treaty architecture. On Friday, President Recep Tayyip Erdoğan, Crown Prince Mohammed bin Salman and Prime Minister Shehbaz Sharif signed the Mecca Joint Deterrence Agreement, under which an armed attack on any one of Turkey, Saudi Arabia or Pakistan is to be treated as an attack on all three. Erdoğa stressed that the pact targets no country and is open to others; Ankara said it does not conflict with its NATO obligations. Whatever its declared intent, the agreement gives Riyadh a formal instrument for internationalising any Houthi strike on Saudi territory.
Third, restraint in Iraq. Following the 29 July US–Saudi strikes on Popular Mobilisation Forces headquarters, which killed more than twenty people, Badr Organisation leader Hadi al-Amiri publicly urged Iraqi factions to postpone retaliation in Iraq's higher interest — a signal that Tehran's network is not yet moving in unison.
Is this a Renewed Civil War?
The evidence points to a collapsed truce rather than a resumed civil war, though the distance between the two is narrowing quickly.
The case for the darker reading is substantial. Adel Dashela of the Sanaa Center for Strategic Studies argues that the pattern of strikes on Hadramawt and Marib indicates a Houthi drive toward the oil and gas regions of Marib, and that a ground war now appears imminent absent an unlikely diplomatic breakthrough. He cautions that a full-spectrum war would be considerably bloodier than earlier rounds, given the group's accumulated missile capability but its exposure across multiple simultaneous fronts. The researcher Fuad Mussed reads the camp strikes as evidence that Ansar Allah has taken a final decision for open confrontation, ending the "neither war nor peace" condition of the past four years. Members of the Presidential Leadership Council, for their part, have publicly abandoned the language of settlement.
The case against is equally concrete. No confirmed change in lines of control has been recorded. What has occurred is a deep-strike exchange — missiles, drones and reciprocal air action — not manoeuvre warfare for terrain. Ahmed Nagi of the International Crisis Group notes that Riyadh and Aden remain committed to containment and appear to be testing that approach to its limits, while adding that the room for continued restraint is becoming narrow and that current indicators favour further escalation over de-escalation.
There is also a structural point that is easy to miss. The intra-Yemeni civil conflict that many now anticipate has, in one form, already been fought and concluded. In December 2025 the Southern Transitional Council launched an offensive across the south, seizing areas of Hadramawt and al-Mahra and the presidential palace in Aden. A Presidential Leadership Council counter-offensive reversed those gains by January 2026, Aden was retaken on 7 January, STC ministers were expelled from the Council, and a disputed dissolution of the organisation was announced from Riyadh on 9 January. The United Arab Emirates had already withdrawn its forces in 2025. That southern front is currently frozen — and its reactivation, rather than the Marib exchange alone, would mark the true onset of a multi-sided civil war.
