Medvedev calls for tightening of nuclear safety rules
Medvedev spoke alongside Ukrainian President Viktor Yanukovich at a solemn ceremony marking the 25th anniversary of the world’s worst nuclear accident at Chernobyl in Ukraine when a reactor exploded, sending radiation billowing across Europe.
The ceremony, at which the two leaders paid homage to the clean-up workers and victims of the 1986 accident, took on added significance amid efforts by Japan to control the crisis at its Fukushima plant, damaged by an earthquake and tsunami.
