Saudi Arabia has faced a series of targeted attacks claimed by Iran-backed Houthi forces over the weekend, including strikes on King Khalid International Airport in the capital that left 12 people dead and more than 300 wounded. The assault on the country’s main airport marked the deadliest incident of its kind in the kingdom in more than a decade and prompted several diplomatic missions to advise their citizens to avoid the facility.
The violence has once again highlighted the persistent security challenges facing the oil-rich state despite its substantial military resources. The renewed hostilities follow the collapse earlier this year of a truce between the Houthis, who control roughly one-third of Yemen’s territory and a large majority of its population, and the Saudi-backed Yemeni government. After the Houthis seized additional strategic areas along the Red Sea coast last month, Saudi Arabia intensified its military involvement in support of the Yemeni government.
The Houthis responded with a series of cross-border strikes aimed at critical infrastructure inside the kingdom, including oil facilities and tourism-related sites. These developments have reversed a period of relative calm and returned the conflict to the centre of regional attention. Despite maintaining one of the most heavily funded militaries in the region—with defence spending reaching approximately 83 billion dollars, or about 6.5 per cent of gross domestic product, in 2025—Saudi Arabia has struggled to fully prevent these incidents.
The kingdom has invested extensively in advanced equipment and training over many years, yet the repeated strikes have exposed gaps in its ability to protect key civilian and economic targets. Analysts note that the nature of the threat, involving actors operating from across a porous border and employing asymmetric tactics, continues to test even well-resourced conventional forces.
The attacks have also affected Saudi Arabia’s carefully cultivated image of stability and security. Crown Prince Mohammed bin Salman has invested heavily in positioning the kingdom as a safe destination for international investment, tourism and business as part of a broader effort to diversify the economy away from oil dependence under the Vision 2030 programme. Persistent security incidents risk undermining investor confidence and complicating long-term economic plans that rely on perceptions of safety and predictability. Diplomatic missions’ warnings to their citizens further amplify the reputational impact at a time when Riyadh is seeking to attract global capital and visitors.

Beyond the immediate human and material costs, the situation underscores broader strategic difficulties. Saudi Arabia’s military doctrine and force structure have traditionally been oriented toward conventional state-based threats, while the Houthi campaign has demonstrated the challenges of defending a long and complex border against non-state actors with external support. The kingdom’s leadership has repeatedly emphasised the need to protect its territory and citizens, yet the continued ability of the Houthis to project force across the border has raised questions about the effectiveness of existing defensive arrangements and the sustainability of the current approach in Yemen.
As both sides continue to exchange strikes, the conflict has once again drawn international attention to the human and economic toll of the long-running war in Yemen and its spillover effects. Regional and global powers continue to call for de-escalation and a return to political negotiations, though prospects for a durable settlement remain uncertain. For Saudi Arabia, the latest wave of attacks serves as a reminder that even substantial financial investment in defence does not automatically translate into comprehensive security against every form of threat. The coming weeks are likely to test the kingdom’s ability to restore calm, protect critical infrastructure and preserve the narrative of stability that underpins its economic transformation agenda.
