Reuters has called for an investigation into the death of TV news cameraman Fadel Shana, who was apparently killed by Israeli troops in the Gaza Strip Wednesday as he attempted to film their tank in an area where violence had broken out. Video taken by Shana shows the tank opening fire -- then going blank seconds later. A Reuters soundman standing next to Shana was wounded by shrapnel. Reuters said that the two men had were standing next to their unarmored vehicle, which bore "TV" and "Press" markings." An Israeli military spokesman expressed sorrow over the death of the cameraman but warned, "The presence of media, photographers and other uninvolved individuals in areas of warfare is extremely dangerous and poses a threat to their lives."
