Chernobyl victims commemorated in Europe

People take part in a ceremony to honour victims of the Chernobyl disaster, the world's worst civil nuclear accident, in the Siberian city of Krasnoyarsk, April 26, 2010. People gathered to commemorate the workers, known locally as "liquidators", who were exposed to large doses of radioactivity during their efforts to contain radioactive contamination when the fourth reactor of the Chernobyl power station exploded in 1986. The sign reads, "Chernobyl". [Agencies]
