Iran and Bahrain Desalination Plant Attacks Escalate Gulf Water Security Concerns

Recent attacks targeting water desalination plants in Iran and Bahrain are raising alarm over the vulnerability of critical infrastructure in the Middle East and escalating regional tensions. These facilities, vital for providing freshwater in arid climates, are increasingly becoming focal points in the ongoing conflict, threatening the water supply for millions.

Attacks and Accusations

On March 8, 2026, Bahrain’s Ministry of Interior reported that an Iranian drone attack damaged a desalination plant, injuring three people. The ministry stated that the attack involved “randomly bombing civilian targets” and caused material damage to the plant, which processes seawater for freshwater supply.

Prior to this, on March 7, 2026, Iran accused the United States of striking a desalination plant on Qeshm Island, impacting the water supply to approximately 30 villages. The U.S. And Israel have denied these accusations.

Reports as well indicate damage at the Doha West power and desalination plant in Kuwait, potentially resulting from attacks or debris from intercepted drones. Similar damage has been reported at the Fujairah F1 power and water complex in the United Arab Emirates, following attacks in the vicinity. Attacks targeting the port of Jebel Ali in Dubai landed approximately 20 kilometers from a major desalination plant.

Escalation of Conflict and International Law

Experts view the attacks on desalination plants as a significant escalation in the conflict. Neil Quilliam, associate fellow at Chatham House, stated that Iran is shifting its focus from targeting economic assets to infrastructure that directly impacts the livelihoods of citizens in Gulf states.

Deliberate attacks on civilian water infrastructure are prohibited under international humanitarian law. Article 54 of Additional Protocol I to the Geneva Conventions explicitly protects drinking water installations from attack, and intentional strikes on such facilities can constitute war crimes under the Rome Statute of the International Criminal Court.

Gulf States’ Reliance on Desalination

The Gulf states are heavily reliant on desalination for their freshwater supply, with approximately 400 plants in the region producing around 40% of the world’s desalinated water. Bahrain is particularly vulnerable, as it generates the majority of its drinking water from these plants.

Kuwait obtains around 90% of its drinking water through desalination, while Oman and Saudi Arabia rely on it for approximately 86% and 70% of their water supply, respectively. Approximately 60 million people live in these countries.

Historical Vulnerability and Future Concerns

Desalination plants have long been recognized as a potential weak point in the region. During the Gulf War in the 1990s, such facilities were previously targeted. A leaked U.S. Diplomatic document from 2008 warned that the Saudi city of Riyadh could face evacuation within a week if the desalination plant in Jubail or associated infrastructure were severely damaged.

While Saudi Arabia and the United Arab Emirates have invested in backup systems, smaller states like Bahrain, Qatar, and Kuwait have limited reserves. The attacks highlight the urgent necessitate for enhanced protection of critical water infrastructure in the region.

Water Security and Regional Stability

The targeting of desalination plants represents a shift towards attacks that directly threaten the daily lives of civilians, potentially exacerbating regional instability. The attacks underscore the interconnectedness of water security and broader geopolitical concerns in the Middle East.
