Iran's attacks on the United Arab Emirates and shipping in and around the Strait of Hormuz will significantly stress the fragile U.S.- Iranian ceasefire, increasing the risk of renewed direct hostilities that would likely include the tit-for-tat targeting of regional critical energy and civilian infrastructure. The United Arab Emirates' Ministry of Defense said on May 4 that the country had come under attack by Iranian drones and missiles, with Emirati air defenses actively engaging incoming threats. Iranian projectiles appear to have triggered a fire at an oil facility in Fujairah, while multiple commercial vessels were also targeted, including a South Korean-operated ship that reportedly suffered a fire and explosion. Separately, U.S. Admiral Brad Cooper told reporters that several U.S. destroyers had transited the Strait of Hormuz and were operating inside the Persian Gulf.
