Since February 28, the US-Iran war has escalated from military and oil targets to critical water infrastructure across the Gulf, now reaching the United Arab Emirates. Key incidents include a March 8 Iranian drone strike on a Bahrain desalination plant, an April 3 attack on Kuwait power and desalination plants with the Mina al-Ahmadi oil refinery, April 5 strikes on two Kuwait power and water desalination plants plus Bahrain's Bapco oil storage, and April 7 Iranian missiles and drones targeting UAE air defenses and infrastructure. On April 7, the Islamic Revolutionary Guard Corps declared that its prior restraint in targeting oil infrastructure and civilian sites in Gulf states 'no longer applies,' marking an explicit escalation threshold after a US strike on Iran's Kharg Island oil export hub.
Gulf states depend on desalination for survival, with Bahrain sourcing 60 percent of its water from such plants and the region holding 60 percent of global desalination capacity. Iran's attacks, now spanning Bahrain, Kuwait, and UAE with repeated hits on power-desalination complexes essential for water production, combined with the IRGC's declaration ending restraint, risk an imminent humanitarian crisis in the world's most water-scarce region. Tit-for-tat strikes are broadening to civilian essentials with no diplomatic off-ramp visible.
