Chernobyl Anniversary

Ukrainians held candlelit vigils to mark 30 years since the world's worst nuclear accident - as Chernobyl spewed radiation across Europe and left several thousand people dead or dying.

At least 30 people were killed on site and several thousand more are feared to have died from the radiation fallout in one of the world's worst man-made disasters, which forced a global rethink about the wisdom of relying on atomic fuel.

The exact number of dead remains a subject of intense debate because the Soviet authorities kept most of the information about Chernobyl under wraps.
