Iran's Islamic Revolutionary Guard Corps (IRGC) said it destroyed a U.S. missile defense radar in the United Arab Emirates and struck a U.S. naval vessel in the Indian Ocean, state-affiliated Tasnim news agency reported Monday.

The Islamic Revolutionary Guard Corps said a precision missile destroyed a radar of the Terminal High Altitude Area Defense (THAAD) in Al-Ruwais, Tasnim reported, citing the IRGC.

In a separate strike, a U.S. carrier group refueling ship was hit by drone and missile fire 700 km off Iran's southeastern city of Chabahar, leaving it "non-operational," the report said.

Tasnim said IRGC anti-submarine missile units are tracking the U.S. naval fleet in the region. It provided no further details.

The strikes are part of what Iran calls "Operation True Promise 4," retaliatory attacks following joint U.S.-Israeli strikes on Saturday that killed Iran's Supreme Leader Ali Khamenei, several other high-ranking officials, and more than 100 civilians.

The IRGC has announced multiple waves of strikes targeting U.S. and Israeli assets across the region, including bases in Kuwait, Iraq, and Saudi Arabia.

U.S. Central Command has not confirmed the Iranian claims.
