One week after Israel's strike on Iran's South Pars gas field sparked retaliatory attacks on Gulf energy facilities, U.S. President Donald Trump issued a 48-hour ultimatum to reopen the Strait of Hormuz, while Iran rejected a cease-fire offer on March 25. The escalating conflict is crippling water security, with strikes damaging desalination plants vital to Qatar, Bahrain, and Kuwait.
The conflict began on March 18, 2026, when Israel targeted Iran's South Pars—the world's largest natural gas field, shared with Qatar and supplying 90% of Iran's domestic energy—leading to Iranian strikes on regional infrastructure, including Qatar's Ras Laffan LNG facility. As detailed in prior coverage, these attacks caused Brent crude prices to surge past $115 per barrel (peaking near $120 before easing below $100) and raised fears over global supplies via the Strait of Hormuz.
New escalations over the weekend saw Trump demand Iran reopen the strait within 48 hours or face U.S. strikes on its power plants. Iran responded by threatening Gulf energy and water systems and rejecting a cease-fire proposal on March 25.
The assaults have extended to water desalination plants, which provide at least half of drinking water in Qatar, Bahrain, and Kuwait. Kaveh Madani, a water researcher at the United Nations University and former Iranian deputy vice president, called it a 'war on infrastructure' worsening Iran's 'water bankruptcy' from six years of drought, overpumping, and mismanagement. Peter Gleick of the Pacific Institute highlighted vulnerabilities in Gulf desalination systems lacking alternatives or storage. Power disruptions could halt Iran's water treatment, while potential oil spills and toxins from explosions endanger fisheries and farms.
Compounding shortages, Iran has banned food exports since March 3 to secure domestic supplies, distorting production and risking inflation, per David Michel of the Center for Strategic and International Studies.
