The United States began a mission to "guide" stranded vessels through the Strait of Hormuz, calling on them to transit in waters near Oman through an "enhanced security area" that could include guided-missile destroyers, aircraft and increased troop presence, though details are limited, AP reported on May 4. The same day, Iran reportedly launched attacks on commercial vessels and U.S. military vessels, as well as targeted the United Arab Emirates in a missile and drone attack.
