A group of Japanese peace activists pay their respects to victims of the Nanjing Massacre in the capital of Jiangsu province on Thursday, the 68th anniversary of Japan's surrender in World War II. At least 300,000 Chinese people were killed by Japanese soldiers when they took Nanjing, then China's capital, in December 1937, in a six-week rampage of looting, rape, torture and murder. The signs read: "In memory of the dead." Liu Jianhua / for China Daily
