The US military has defended its decision to drop the country's most powerful non-nuclear bomb on ISIS positions in Afghanistan, describing it as a "tactical" move. The GBU-43/B Massive Ordinance Air Blast bomb (MOAB) was dropped Thursday night on a network of fortified underground tunnels that ISIS had been using to stage attacks on government forces. The strike, in Nangarhar province near the Pakistan border, also killed 36 ISIS's, Afghan officials say. The US military was quizzed Friday on whether the munition, known as the "mother of all bombs" for its extraordinary force, was necessary for the particular target. The GPS-guided bomb is capable of destroying an area equivalent to nine city blocks. "This was the right weapon against the right target," the commander for US forces in Afghanistan, General John Nicholson, told a press conference. "It was the right time to use it tactically against the right target on the battlefield."
