At least 90 Islamic State terrorists were killed by a huge bomb dropped by the United States in Afghanistan. The Governor of the Achin Province, Ismail Shinwary gave this information. The most powerful non-nuclear bomb ever used by the US in combat was dropped on an IS base in Achin district of Nangarhar, bordering Pakistan. <br/><br/>US official said, a network of tunnels and caves was destroyed when US military aircraft dropped the 22,000-pound GBU-43-Massive Ordnance Air Blast bomb (MOAB), the Mother of All Bombs. The bomb was dropped after fighting intensified over the past week and US-backed ground forces struggled to advance on the area. Afghan President Ashraf Ghani's office said in a statement the attack was a part of a joint operation by Afghan and international troops. <br/><br/>The strike came as U.S. President Donald Trump prepares to dispatch his first high-level delegation to Kabul, amid uncertainty about his plans for the nearly 9,000 American troops stationed in Afghanistan.
