Two US officials told The Wall Street Journal that over the weekend, American Northrop Grumman B-2 Spirit bombers dropped heavy GBU-57 Massive Ordnance Penetrator bombs, known as the “mother of all bunker busters," on an underground complex belonging to the Islamic Revolutionary Guard Corps.
According to one of the officials, the facility was destroyed in the strike, and several members of the IRGC were killed.
