100 Afghan civilians killed

"In court testimony Saturday, a government witness testifying against Manning said that Lamo subsequently contacted authorities in July 2010 to say that he’d learned through online chats that a person named Jason Katz who worked at a Department of Energy lab had tried to help WikiLeaks decrypt a video of the2009 Garani incident, in which U.S. warplanes allegedly killed nearly 100 Afghan civilians."
