In current time, Ukraine is marking the 25th anniversary of nuclear accident at Chernobyl power plant, which is considered the worst accident in the history of nuclear power.
On April 26, 1986, the No. 4 reactor at the Chernobyl plant in the border of Ukraine-Belarus exploded and caught fire for days afterwards. Thirty-one people were killed immediately while nearly 4,400 people lost their life due to radiation-related sicknesses. Tens of thousands residents were forced to flee from a highly contaminated area and never returned. The explosion had sent radiation billowing across Russian Federation, Ukraine and Belarus. 25 years has passed away, but the town closest to the site Prypyat has still been abandoned as a ghost town. Thousand of houses have not been inhabited and left to fall into ruin.

This image captures one of the closest buildings near the Chernobyl power plant in the deserted city of Pripyat.

The bumper cars have still been in a fairground in Pripyat. After the nuclear leak, 30-kilometer area around the plant has been uninhabited.

Some local residents return back to their home despite the warnings from governments and officials.
