After the bombing of a hospital in Afghanistan, Doctors Without Borders has accused the US military of a war crime. Today in Washington, the commander of US and allied forces appeared before a Senate committee. Army General John F. Campbell testified, "On Saturday morning our forces provided close air support to Afghan forces at their request. To be clear, the decision to provide aerial fires was a US decision made within the US chain of command. A hospital was mistakenly struck. We would never intentionally target a protected medical facility." Missy Ryan, Pentagon reporter for the Washington Post, has an update.
