The ongoing conflict in the Middle East has entered a perilous new chapter, with recent attacks on desalination plants marking a troubling escalation. As these critical facilities provide drinking water to millions in a region already grappling with severe water scarcity, experts warn that the weaponisation of water infrastructure presents an existential threat to numerous nations across the Arabian Peninsula.
Desalination: A Lifeline for the Gulf
In a region characterised by its arid landscape, the scarcity of natural freshwater sources makes desalination plants not merely important, but vital. These facilities are the backbone of water supply for countries such as Kuwait, the United Arab Emirates, Oman, and Saudi Arabia, with reliance on desalination reaching as high as 90 per cent in some areas. With no rivers or significant rainfall, these nations have invested heavily in technology to convert seawater into potable water, making the recent assaults on such infrastructure deeply concerning.
On Sunday, Bahrain accused Iran of launching a drone strike against one of its desalination facilities. This incident followed claims from Iran that the United States had targeted a desalination plant on Qeshm Island, cutting off water supplies to 30 villages. Such actions represent a chilling new strategy in the ongoing conflict, where water is now a weapon of choice.
A Dangerous Precedent
Iran’s foreign minister, Abbas Araghchi, has condemned the US for what he termed “a blatant and desperate crime,” asserting that the precedent set by attacking a freshwater plant could have dire consequences for civilian infrastructure across the region. While the US has not confirmed the attack, President Donald Trump appeared dismissive, suggesting that such concerns were trivial compared to other, more severe issues.

David Michel, a senior fellow for water security at the Centre for Strategic and International Studies, emphasised the gravity of this situation, stating that the intentional targeting of water infrastructure marks a significant shift in tactics. “As the conflict continues,” he warned, “there may be increased intent or pressure on decision-makers to escalate their actions against civilian targets.”
Fragile Lifelines
Experts are sounding alarms over the vulnerability of desalination plants, which are poorly defended despite being crucial to the survival of millions. Lalit Mohan, a water management consultant, pointed out that damage to any segment of a desalination facility can halt water delivery entirely. Furthermore, many plants are linked to power stations, meaning that an attack on electrical infrastructure could be just as devastating.
Ed Cullinane, editor at Global Water Intelligence, remarked that desalination plants are as exposed as other civilian targets in the Gulf. “They are large open facilities, no different from oil terminals or ports, and are equally susceptible to military action,” he stated. The prospect of cyberattacks also looms large, with Iran having previously demonstrated its ability to infiltrate water systems in other countries.
A Broader Humanitarian Crisis
While the immediate implications of these attacks are dire, the long-term consequences could be even more severe. The World Resources Institute’s Aqueduct Water Risk Atlas shows that 83 per cent of the Middle East’s population already faces severe water scarcity. Iran, in particular, is confronting a worsening water crisis, with depleted reservoirs and rivers competing with urban demands. President Masoud Pezeshkian has warned that Tehran could face a humanitarian crisis if water shortages continue to escalate.

Legal experts have raised concerns about the implications of targeting civilian infrastructure under international humanitarian law. Dr Evelyne Schmid, a professor at the University of Lausanne, stated, “Desalination plants are civilian objects – targeting them constitutes a serious violation of international law.”
Why it Matters
The weaponisation of water infrastructure not only poses a risk to the immediate population but also threatens to destabilise the entire region. As access to water becomes increasingly compromised, civilian populations may find themselves caught in an untenable situation, faced with the choice of staying in a conflict-ridden area or fleeing in search of basic necessities. This situation underscores the urgent need for regional cooperation and a unified strategy to protect critical water resources, highlighting the necessity of dialogue in a region fraught with mistrust. Without decisive action, the consequences could spiral into a humanitarian disaster, affecting millions and destabilising nations already on the brink.
