The Houthis’ latest strikes on Aden, Saudi Arabia, airports, and oil infrastructure show that the war in Yemen is no longer solely an internal conflict. The Ansar Allah movement has significantly expanded its military capabilities and can now simultaneously pressure Yemen’s internationally recognized government, threaten Saudi cities, and create risks for shipping in the Red Sea. At the same time, Iran is believed by a number of experts to be helping the Houthis with technology, intelligence, and training, although Tehran officially denies direct involvement.

The attacks on Aden have particular political significance. After the Houthis seized Sana’a in 2014, Aden became the temporary capital of the internationally recognized government. Therefore, the strike on al-Maashiq Palace was not only a military operation but also a demonstration of the vulnerability of the Houthis’ opponents’ political center itself. As Al Jazeera reports, five missiles hit the grounds of the presidential palace, killing five people and injuring 16. Prime Minister Shayea al-Zindani and other officials were unharmed, but guards and civilian employees were among those killed.

The following day, two missiles landed on the grounds of Aden International Airport as a Yemenia passenger plane was preparing to depart for Cairo. According to Yemeni authorities, the munitions exploded approximately 500 meters from the aircraft. There were no casualties, but the attack on a civilian airport underscores how closely military and civilian sites are intertwined in Yemen. The Houthis said the targets were a military headquarters and weapons depots at a neighboring base, but for passengers and aviation crews, this distinction does little to reduce the danger.

The attack on Aden was part of a broader escalation. Following the 2022 truce, the fronts in Yemen remained largely frozen, but fighting resumed in the summer of 2026. The Houthis launched an offensive along the Red Sea coast and seized positions controlling approaches to the Bab el-Mandeb Strait. This strait is a narrow maritime passage between Yemen and Africa through which a significant share of global trade passes. Control of it allows the Houthis to threaten not only their opponents inside Yemen but also international shipping, oil routes, and military logistics.

In response, Yemen’s Presidential Council announced Operation Yemen Dawn, aimed at retaking captured territories, including Sana’a. The Saudi-led coalition publicly confirmed the resumption of airstrikes for the first time since 2022 and said that around 100 combat aircraft were involved. So far, however, air power has failed to change the situation on the ground. As The Associated Press writes, the Houthis continue to hold substantial territory and have demonstrated the ability to strike hundreds of kilometers from Yemen.

The attacks on Saudi Arabia are particularly revealing. The Houthis have repeatedly targeted King Khalid International Airport in Riyadh, the headquarters of oil company Saudi Aramco, and other facilities. This has led to flight cancellations, loss of life, and disruptions to everyday life. Saudi Arabia’s vulnerability is partly explained by the country’s size: key airports, oil facilities, and pipelines are spread across a vast territory, while the border with Yemen stretches for more than 1,300 kilometers.

Saudi Arabia’s military advantage proved less decisive than expected. The kingdom has modern American aircraft, missile-defense systems, and precision-guided weapons, but the Houthis use inexpensive drones and missiles capable of damaging infrastructure whose value is far greater. This asymmetry means the attacking side can spend relatively little while forcing its opponent to expend costly interceptor missiles and maintain a constant high level of readiness.

According to AP, the Houthis’ arsenal includes ballistic and cruise missiles, attack drones, anti-ship missiles, and maritime drones. Some of these systems resemble Iranian designs. UN experts have also documented military links between the Houthis, Iran, and other allies of Tehran. The movement’s numbers are estimated to have grown from roughly 30,000 fighters in 2015 to 350,000 by 2024. This reflects not only external support but also the transformation of the Houthis into a mass military-political structure capable of independently producing some weapons and replacing its losses.

Intelligence is another dimension of the conflict. Citing a report by The Wall Street Journal, The Jerusalem Post reports that Iran may have provided the Houthis with targeting information for missile and drone attacks. Danny Citrinowicz, a former Israeli military intelligence officer, described operational ties between Tehran and the Houthis as “very, very strong.” In his view, this is not simply a classic client-patron relationship but “strategic cooperation”: Houthi successes weaken Saudi Arabia, increase risks to oil supplies, and allow Iran to expand its influence without directly entering the war.

The Soufan Center also supports this logic, arguing that the attacks help Iran “project power.” Power projection refers to a state’s ability to influence events far beyond its own borders through allies, armed groups, military technology, or political pressure. Iran may deny directly commanding the operations while still gaining strategic benefits from Houthi actions.

Tehran has consistently rejected the allegations. Iranian Foreign Ministry spokesman Esmaeil Baghaei has said that the Houthis are “completely independent actors” who make decisions based on their own interests. Iran also denies supplying weapons, as this would violate the UN arms embargo. However, the existence of a connection does not necessarily mean that Tehran issues direct orders. Support may include the delivery of components, training, the exchange of expertise, technical advice, and the transfer of intelligence. This model allows Iran to maintain deniability while simultaneously increasing pressure on Saudi Arabia.

It is precisely the combination of Iranian assistance and the Houthis’ independent development that makes them particularly dangerous. In a Jerusalem Post article, Yemen expert Adam Baron called the impact of external support on the movement’s recent successes “undeniable.” At the same time, the Houthis do not appear to be passive instruments of Tehran. They have their own agenda: fighting the internationally recognized government, confronting Saudi Arabia, and seeking to consolidate control over northern and western Yemen. Iranian support strengthens these goals but does not necessarily determine them entirely.

Geography plays an important role. The Houthis operate in mountainous and inaccessible terrain, where warehouses, launchers, and command centers can be easily dispersed. Airstrikes can destroy individual sites but cannot reliably eliminate a network of mobile units. For this reason, decisively defeating the movement would require a ground operation. However, the Houthis’ opponents lack a unified front: the internationally recognized government, southern separatists, and various local armed groups pursue different objectives and sometimes fight one another.

This explains why years of air campaigns by Saudi Arabia, the United States, the United Kingdom, and Israel have not produced a strategic breakthrough. According to AP, the Houthis have grown stronger over the years of war despite airstrikes and the blockade. Air power can destroy infrastructure and slow an offensive, but it cannot replace control of territory, governance of the population, and the ability to hold captured areas.

The new escalation has consequences far beyond Yemen. The threat to the Bab el-Mandeb Strait raises insurance and shipping costs, creates risks for oil exports, and could force vessels to choose longer routes. If problems arise simultaneously in the Strait of Hormuz and the Red Sea, energy markets will suffer a double shock. In that case, a local war becomes a factor in global economic instability.

The response of international organizations reflects precisely this risk. The UN Security Council condemned Houthi attacks on Saudi Arabia, including strikes on civil aviation and energy infrastructure. The Council of the International Civil Aviation Organization also condemned the attacks on airports and aircraft. UN Special Envoy for Yemen Hans Grundberg said that the country had returned to “full-scale war.” This is an important assessment: the issue is no longer isolated breaches of a truce but the collapse of the previous system of deterrence.

Saudi Arabia accuses Iran of pushing the Houthis toward escalation and claims that the movement rejected an offer of talks in Oman. Iran denies this and has simultaneously offered its own “good offices” to end the fighting. This position is typical of regional rivalry: Tehran seeks to act as a mediator while remaining politically connected to one side of the conflict. Canada called for immediate de-escalation and expressed support for Yemen’s internationally recognized government.

The main conclusion is that the Houthis have become an independent regional actor whose capabilities cannot be explained solely by Yemen’s internal crisis. They use local geography, mass mobilization, inexpensive strike systems, and external technologies to offset their opponent’s superiority in air power and finances. Iran gains strategic dividends from this instrument of pressure, but direct control over the Houthis remains unproven and is officially denied.

The prospects for a settlement appear limited. Saudi Arabia cannot lift the blockade without losing face while simultaneously acknowledging political defeat, whereas the Houthis demand an end to the pressure and are prepared to use their control of the coast as a coercive tool. A ground offensive is complicated by the fragmentation of anti-Houthi forces, while further airstrikes could worsen the humanitarian catastrophe without eliminating the military threat.

Thus, the strikes on Aden and Saudi Arabia should be viewed as parts of a single strategy. The Houthis seek simultaneously to undermine the legitimacy of Yemen’s government, punish its external allies, threaten regional transport routes, and demonstrate that a decade of military pressure has failed to break them. If diplomacy is not restored, Yemen risks becoming a permanent flashpoint in the confrontation between Iran, Saudi Arabia, and other regional powers—with consequences for civilians, energy markets, and international shipping.
