Dark lens: Chinese volunteer soldiers slaughtered by Japanese troops

This undated file photo shows the slaughter of Chinese volunteer soldiers conducted by Japanese troops in China. On Sept. 18, 1931, Japanese troops blew up a section of the railway under their control near Shenyang, capital of northeast China's Liaoning Province, and then accused Chinese troops of sabotage as a pretext for attack. They bombarded barracks near Shenyang the same evening, beginning a large-scale armed invasion of northeast China. The incident was followed by Japan's full-scale invasion of China and the rest of Asia, triggering the war against Japanese aggression. (Xinhua)
