Iranian military adviser Mohsen Rezaei has claimed that more than 500 U.S. troops were killed in recent fighting, with total American casualties reaching around 650, including those wounded. The United States has not confirmed these figures, and they remain unverified. The remarks come amid heightened tensions between Washington and Tehran, continued military activity around the Strait of Hormuz, and reports of renewed diplomatic contacts. Meanwhile, Iran's Foreign Ministry spokesperson Esmail Baghaei said Tehran is not currently holding negotiations with the United States.
