Skeletons of victims of the Nanjing Massacre are seen at the Nanjing Massacre Museum, Jiangsu province December 13, 2012. China marked 75 years since the Nanjing massacre, also known as the "Rape of Nanking", in which China says Japanese troops killed 300,000 people in what was then the national capital. A postwar Allied tribunal put the death toll at 142,000, but some conservative Japanese politicians and scholars deny a massacre took place.
