The United States used a special Hellfire missile, dubbed “the flying Ginsu,” in a retaliatory airstrike against the Islamic State militants in Afghanistan over the weekend, following a suicide bomb attack in Kabul that left 13 US soldiers dead. The missile, which was transported by a Reaper drone, is called an R9X and packs no explosives. It instead ejects six large blades at the target of the strike to help reduce civilian casualties. Its nickname is a nod to the popular knives sold on TV infomercials during the 1980s with the same name. It has also reportedly been referred to as the “ninja bomb.” Its use had not previously been disclosed, according to the Wall Street Journal, citing two US officials. In a statement, US Central Command said the operation targeted a “planner” for ISIS-K, the group also known as the Islamic State Khorasan, which took credit for the deadly bombing attack. While the Pentagon has not released the identities of the individuals targeted, the airstrike killed two people with ties to the Islamic State and injured another Saturday. The strike site was in the Nangarhar province in eastern Afghanistan.
