China marks Nanjing massacre amid tense Japan ties
Air raid sirens sounded in the Chinese city of Nanjing today as it marked the 75th anniversary of a killing spree by Japanese soldiers.
The ceremony at the Nanjing Massacre Museum was attended by 9,000 people.
It began with the singing of China's national anthem as soldiers in dress uniforms carried large wreaths across a stage.
China says 300,000 civilians and soldiers died in a spree of killing, rape and destruction in the six weeks after the Japanese military entered the then-capital on this day in 1937.
The 75th anniversary has taken on added meaning given the poor state of bilateral ties.
Protests against Japan erupted in Chinese cities earlier this year over the status of disputed islands in the East China Sea.
