On Wednesday, a suicide bomber killed eight American civilians in Afghanistan, according to U.S. officials. The incident happened at Forward Operating Base Chapman, which is located in a highly hostile area near the Pakistan border. It is still unclear how many people were injured and whether or not the bomber was targeting the civilians, reportedly CIA employees. With the latest is Marvin Weinbaum, former State Department analyst on Afghanistan and Pakistan, along with Peter Greste, BBC correspondent in Afghanistan.
