It is 30 years today since the accident at the Chernobyl nuclear plant, in what is now the Ukraine but was then part of the USSR, shook the world.
An explosion at the nuclear reactor on 26 April 1986 caused a cloud of radioactive material drifted far and wide across the then USSR and also Europe, effecting people, wildlife and land.
Between 1986 to 2000, 350,400 people were evacuated and resettled from the most severely contaminated areas.
Vigils have been held across the Ukraine today to mark this day in history.
