The Islamic Revolutionary Guard Corps stated Tuesday that more than 650 US military personnel were killed or wounded during the first two days of Iran's retaliatory Operation True Promise-4, as Iranian forces attacked American bases and warships across the region, Tasnim reports.

According to IRGC spokesman Brigadier General Ali Mohammad Naeini, the strikes — which included missile and drone attacks on US Navy facilities and military headquarters in Bahrain — forced the aircraft carrier USS Abraham Lincoln to retreat from Iranian coastal waters. The spokesman confirmed that Iranian armed forces inflicted heavy casualties on US military facilities in the Persian Gulf region.

"In the first two days of the war, 650 American military personnel were killed or wounded," General Naeini stated.

He acknowledged it was "natural for Americans to deny or conceal these losses," but noted that Iranian intelligence and combat reports confirm the figures.

Naeini detailed that Iranian missiles and drones repeatedly struck the headquarters of the US Navy's Fifth Fleet in Bahrain. In one attack, he said, 160 US personnel were killed or wounded when Iranian forces struck a key American military facility in the country.

Additionally, according to the report, a US Navy MST combat support vessel sustained heavy damage after being hit by Iranian naval missiles.

The IRGC spokesman also reported that Iranian naval forces fired four cruise missiles at the USS Abraham Lincoln, which was approximately 250–300 kilometers off the coast of Chabahar in southeastern Iran. Following the strikes, the carrier "retreated into the southeastern Indian Ocean," Naeini said.
