Belarus's opposition supporters carry flags during a rally in Minsk on April 26, 2009 marking the Chernobyl catastrophe 23 years after the worst nuclear accident in history that occurred in northern Ukraine but affected large areas of Belarus. Over 25,000 people known as "liquidators" -- most of them Ukrainians, Russians and Belarussians -- died getting the accident under control and constructing a concrete shield over the wreckage, according to Ukrainian official figures.
