Students attend a ceremony to commemorate the 84th anniversary of the September 18 Incident in Shenyang, capital of Northeast China's Liaoning province, Sept 18, 2015. On Sept 18, 1931, Japanese troops blew up a section of the railway under their control near Shenyang, 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. [Photo/Xinhua]
