The United States dropped a massive GBU-43 bomb, also known as the "mother of all bombs," in eastern Afghanistan on Thursday against a series of caves used by ISIS militants, the military said. It was the first time this type of non-nuclear bomb has been used in combat, Pentagon spokesperson Adam Stump said. It was dropped from a MC-130 transport, he said, and the aircraft had been brought to Afghanistan "some time ago" for potential use. When it was developed in the early 2000s the Pentagon did a formal review of legal justification for its combat use. He said ISIS has been using improvised explosive devices, bunkers and tunnels to strengthen its defences.
