An Iranian attack on an air base in Qatar key to the U.S. military likely hit a geodesic dome housing equipment used by the Americans for secure communications.

New satellite images show Iran’s missile strike on a US military base in Qatar in June destroyed a dome used for secure communications, a key structure at Al Udeid Air Base, which hosts US Central Command’s forward headquarters.

The Pentagon confirmed that one missile got past air defenses, showing a wider extent of damage than had been announced.
