Photo taken on Feb. 22, 2017 shows an abandoned building at Futaba District, Fukushima Prefecture, Japan. A magnitude-9.0 earthquake in 2011 triggered a massive tsunami which destroyed the emergency power and then the cooling system of Fukushima Daiichi nuclear power plant, and caused a serious nuclear disaster, forcing some 300,000 people to evacuate. Almost six years later, the nuclear nightmare still continues in that part of Japan. (Xinhua/Hua Yi)
