Takeoka Chisaka, Hiroshima, Japan. “One morning in August 1945, I was walking home from the night shift at a factory in Hiroshima. As I reached my door, there was a huge explosion. When I came to, my head was bleeding and I had been blasted 30m away. The atomic bomb had detonated. When I found my mother, her eyes were badly burned. A doctor said they had to come out, but he didn’t have the proper tools so used a knife instead. It was hellish. I became a peace-worker after the war. In the 1960s, at a meeting at the UN, I met one of the people who created the atomic bomb. He apologised”. (Photo and caption by Sasha Maslov)

Reuters photographer Bobby Yip took a series of portraits of people taking part in the “Occupy Central” protests in Hong Kong, and asked them why they had joined the demonstrations. China rules Hong Kong under a “one country, two systems” formula that accords the territory limited democracy. Tens of thousands of mostly student protesters are demanding Beijing give them full democracy, with the freedom to nominate election candidates. The unrest is the worst in Hong Kong since China resumed its rule over the former British colony in 1997. (Photo by Carlos Barria/Reuters)
