The U.S. military struck multiple Iranian oil tankers linked to the Islamic Revolutionary Guard Corps (IRGC), responding to what a U.S. official described as more attempted Iranian missile launches at U.S. Navy warships. The targeted U.S. vessel has not been identified, and no ships were hit in the reported Monday attack. U.S. forces also struck an oil tanker near Kharg Island in the northern Persian Gulf, according to Tasnim News Agency, a semi-official outlet affiliated with the IRGC. The escalation follows Saturday strikes that permanently disabled three IRGC crude oil tankers near Kharg Island and in the Gulf of Oman, followed by an IRGC attack on a remotely operated U.S. military vessel in the Strait of Hormuz. Iran is set to announce a restricted zone near the strait, with non-cooperating ships to be placed on a sanctions list, Press TV reported. Meanwhile, the U.S. military continues enforcing a naval blockade in the Arabian Sea and says it has redirected 94 commercial ships, disabled three and boarded another since mid-July.
