The story
Ukraine has been holding ceremonies to mark the 30th anniversary of Chernobyl, the world's worst nuclear accident. A meltdown in the plant's reactor in April 1986 blew off the roof and sent a cloud of radioactive material across Ukraine's borders into neighbouring Belarus and across a swathe of northern Europe. Relatives of those who died held candlelight vigils at several churches.
Tom Burridge – BBC News
Candles were lit and prayers were said in the early hours of this morning at the moment, 30 years ago, that there was an explosion inside reactor four at the Chernobyl nuclear plant.
Roughly 3% of the reactor's radioactive content escaped.
Later, Ukraine's president will attend another ceremony in Chernobyl to mark the disaster, which contributed to the downfall of the Soviet Union and had a huge impact on public opinion and government policy towards nuclear energy.
