According to Svmuu, on April 26 local time, the Islamic Revolutionary Guard Corps of Iran announced that its special forces had successfully destroyed three American GBU-57 massive bunker-buster bombs and dismantled another one left behind in Iran's Zanjan Province. The GBU-57 bunker-buster bomb (also known as a bunker-busting bomb) is a heavy penetrating bomb developed by the United States. The U.S. used this type of bomb in military operations targeting Iranian nuclear facilities last year and also deployed a large number of these weapons in this year's conflict with Iran. (CCTV)
