A Refinitiv investigation found that since Feb. 28 Iran and Iran-backed militias have carried out at least 135 precision strikes on 84 infrastructure targets across the Gulf, hitting key oil, gas, power and transport facilities. The attacks have caused billions of dollars in damage, disrupted global energy supplies and helped Iran withstand U.S. military pressure. Gulf governments have often downplayed the losses, attributing damage to debris from intercepted missiles and drones.
