Libyan authorities have accused NATO forces of killing 19 civilians, including eight children, in an attack on a home of one of Col. Muammar Gaddafi’s top officials. The accusation came one day after NATO admitted to killing as many as nine civilians in a separate aerial attack. Meanwhile, more details have emerged about the U.S. role in military air attack operations in Libya. While the Obama administration has attempted to downplay the level of hostilities, the New York Times reports U.S. warplanes have bombed Libya about 60 times since the U.S. handed control of the air war to NATO in early April. In addition, U.S. drones have fired missiles at Libyan targets about 30 times.
