Yemen Conflict Risk: UN Envoy Warns of Renewed Large-Scale War Since 2022 Truce
Yemen today faces its most dangerous juncture since the April 2022 UN-brokered truce, with the United Nations’ top diplomat for the country warning that a cascade of Houthi attacks, strikes on civilian infrastructure, and renewed Red Sea shipping assaults could drag the country into a broader regional war. In a statement released on Friday, UN Special Envoy for Yemen Hans Grundberg said,
“Yemen today faces a greater risk of renewed large-scale conflict than at any point since the UN-brokered truce of April 2022,”
adding that
“taken together, these developments risk jeopardizing the gains of the 2022 truce… while also drawing the country into a broader regional confrontation, with devastating consequences for its people.”
A fragile calm under strain: what has changed on the ground
Since more than four years ago, Yemen has been operating on a de facto truce after the official truce agreement of April 2022 expired in October 2022 without any official extension but was maintained in much of the country. This period of calm has resulted in reduced ground combat operations between the Iran-supported Houthis and the Saudi-supported coalition backing the legitimate government.
The current escalation, however, marks a sharp departure. Grundberg cited
“the latest attacks by Ansar Allah in Ma’rib and Hadramawt, which reportedly caused significant casualties, including civilians,”
alongside
“renewed attacks on commercial shipping in the Red Sea and the Gulf of Aden.”
He also flagged “strikes on civilian infrastructure, including airports,” and warned that “heightened regional tensions” magnify the danger of a wider conflagration.
Flashpoints in Ma’rib and Hadramawt: the deadliest escalation since 2022
The fighting has been especially fierce in Ma’rib, the oil-rich province that has traditionally acted as the frontline. According to local authorities and state-run news agency SABA, the Houthis’ missiles and drones hit the displacement camps and residential areas in Ma’rib city on Friday, resulting in the deaths of two people and injuries to 14 more. The previous day, on Thursday, 58 government soldiers reportedly died after being attacked with Houthis’ missiles in Ma’rib province, and some regional sources referred to the incidents as “the deadliest escalation since the 2022 truce.”
The number of victims is rising rapidly. One source mentions that at least 10 people were killed in total as a result of the increased attacks on Ma’rib conducted by the Houthis amid UN warnings, while another described the attacks conducted by the Houthis as “the deadliest escalation since 2022 truce.” From the information provided above, it becomes clear that the events under discussion are not an exception but a rule that poses a threat to stability within the country.
Maritime front: Red Sea attacks and the risk of regional spillover
Similarly disturbing to Grundberg is the recommencement of Houthi attacks against commercial ships in the Red Sea and Gulf of Aden. Even though the Houthis have been intermittently attacking ships since the end of 2023 in light of the Gaza war, a resurgence of these attacks increases the likelihood that Yemen would turn into a battleground within a bigger conflict between the US, Iran, and the Gulf region. These fears have been reinforced through regional intelligence reports as well. According to an unnamed Saudi official interviewed by Reuters, there are indications from intelligence that the Houthi militia along with armed groups from Iraq can attack Saudi Arabia in coordination with Iran’s Islamic Revolutionary Guard Corps.
The envoy’s warning explicitly links internal fighting to external escalation, arguing that
“these developments risk jeopardizing the gains of the 2022 truce… while also drawing the country into a broader regional confrontation, with devastating consequences for its people.”
Civilian infrastructure under fire: airports, camps, and cities
Beyond battlefield casualties, the targeting of civilian infrastructure has drawn particular condemnation. Grundberg expressed concern over “strikes on civilian infrastructure, including airports,” a reference that echoes recent attacks on Sanaa International Airport’s runway and other facilities. The European Union, in a strongly worded statement, said,
“The targeting of civilians and civilian infrastructure is unacceptable and must cease immediately,”
and described the latest wave of Houthi attacks against Saudi Arabia and government areas in Yemen, including strikes in Najran and Ma’rib city, as “a dangerous escalation” that
“further undermine regional stability and risk jeopardising ongoing efforts towards a peaceful resolution of the conflict.”
The humanitarian implications are severe. Yemen’s population has endured more than a decade of conflict, displacement, and economic collapse, with millions dependent on aid. Renewed large-scale fighting would almost certainly worsen food insecurity, disrupt imports, and strain already fragile health services. Grundberg has previously warned that
“Yemen remains highly exposed to the economic repercussions of the regional escalation, and as the global situation has made clear, it is always the poorest and most vulnerable who bear the heaviest burden.”
Diplomatic calculus: calls for restraint and UN-led negotiations
Faced with this escalation, Grundberg’s message is blunt: maximum restraint and a return to political negotiations. He called on all parties to exercise “maximum restraint,” to
“halt actions that could trigger further military retaliation,”
and to engage in
“good-faith negotiations under UN auspices.”
He also noted that he is in intensive discussions with Yemeni parties, regional actors, and international partners to explore de-escalation options, reflecting the high stakes for Gulf states and global shipping lanes.
The UN’s stance is consistent with earlier Security Council briefings. In February 2026, Grundberg told the Council that
“Yemen needs an inclusive political process under UN auspices to reach a negotiated political settlement that can sustainably end the conflict,”
while warning that rising regional tensions risk dragging Yemen back into broader confrontation. In January 2026, he had already urged that Yemen needs “politics rather than force,” as millions were left without life-saving aid and as detention of UN and relief personnel complicated humanitarian access.
Positions of key actors: Houthis, Saudi Arabia, and the international community
This Houthi insurgency movement, officially called Ansar Allah, has put the latest attacks in the context of a bigger plan within the region, stating “escalation for escalation” after the attack on Sanaa airport, followed by the missile and drone attack that started fire in Aramco refinery in Jazan and also targeted oil facilities in the Red Sea city of Yanbu – the first direct Houthi attack on Saudi oil installations in four years. Jasem Albudaiwi, the Secretary-General of the Gulf Cooperation Council (GCC), stated that attacks of this kind represent “heinous terrorist crimes and flagrant violations of international law and international humanitarian law” and also claimed that “they deliberately and indiscriminately target civilians and civilian infrastructure.” The deterrence approach has been used by Saudi Arabia and the coalition forces as well. Colonel Turki Al-Malki, a spokesman for the coalition, accused “Houthi terrorists” of deliberately attacking civilians and civilian infrastructure, breaking international humanitarian law and said that the coalition will keep taking “all deterrent measures” to defend civilians from any more attacks.
Why this warning matters: the stakes for Yemen and the region
The threat of a relapse to full-scale war, as mentioned by Grundberg, is real, and there is a lower bar of entry today than any other time since 2022. This is because the factors of massive casualties in Ma’rib, strikes against displacement camps, attacks on the airports, and resumption of attacks at sea form a cycle where each party feels that it is necessary to retaliate, increasing the possibilities of miscalculations and escalation. The regional component is important. The rising tension between the United States and Iran, coupled with the preparation of the Gulf countries for any joint strikes at energy facilities, ports, and airports, means that Yemen could easily become a theater of a bigger war.
As Grundberg has cautioned,
“Yemenis across the country have long contended with inadequate public services, delayed salaries, and rising prices, and they will now have to contend with import disruptions and higher fuel and food prices triggered by wider conflict in the Middle East.”
Pathways to de-escalation: what the UN is pushing for
The UN’s immediate priority is to halt the spiral of retaliation and create space for negotiations. Grundberg’s call for “good-faith negotiations under UN auspices” is a reminder that, despite years of deadlock, the UN-mediated process remains the only framework with broad international recognition.
This approach will have to take into account both power sharing in Yemen itself and the regional security considerations that have time and again sabotaged any efforts at talks. More concretely, a de-escalation of tensions will have to involve: a stop to assaults against civilians and the destruction of displacement camps; stopping missile and other attacks against commercial shipping, as these tend to pull outside powers into the conflict; and a pledge by all sides not to provoke military reprisal. Otherwise, all the progress achieved through the 2022 truce – evident in the stability maintained within Yemen in recent years – may well be squandered.
