A child gas mask and a doll are seen inside a kindergarten in the abandoned city of Prypiat near the Chernobyl nuclear power plant April 4, 2011. Belarus, Ukraine and Russia will mark the 25th anniversary of the nuclear reactor explosion in Chernobyl, the place where the world's worst civil nuclear accident took place, on April 26. Engineers are still struggling to regain control of damaged reactors at the Fuskushima plant after last month's earthquake and tsunami, in the worst nuclear crisis since Chernobyl in 1986, with the government urging the operator of the plant to act faster to stop radiation spreading.

epa02687012 (03/25) A view of rusty bumper cars in the deserted town of Pripyat, near the Chernobyl Nuclear Power Plant, Ukraine, 22 March 2011. On 26 April 1986, a nuclear accident occurred at Unit 4 of the Chernobyl Nuclear Power Plant in the former Ukrainian Republic of the Soviet Union. Twenty-five years after the Chernobyl disaster, the contaminated zone with the abandoned town of Pripyat has become a popular tourist destination for numerous visitors. Pripyat was built in 1970 to house employees of the nearby Chernobyl Nuclear Power Plant and their families. Some 50,000 residents from and around Pripyat have been evacuated after the 1986 accident. The 25th anniversary of what is considered the world's worst nuclear power plant accident in history is marked on 26 April 2011.
