U.S. forces in Afghanistan on Thursday struck an Islamic State tunnel complex in eastern Afghanistan with “the mother of all bombs,” the largest non-nuclear weapon every used in combat by the U.S. military, Pentagon officials said.
The bomb, known officially as a GBU-43B, or massive ordnance air blast weapon, unleashes 11 tons of explosives. When it was developed in the early 2000s the Pentagon did a formal review of legal justification for its combat use.
The U.S. military headquarters in Kabul said in a statement that the bomb was dropped at 7:32 p.m. local time Thursday on a tunnel complex in Achin district of Nangarhar province, where the Afghan affiliate of the Islamic State group has been operating.
