KYIV, March 7 – Russia, by shelling and seizing nuclear facilities in Ukraine, is increasing the risk of a worldwide nuclear disaster every day, Energy Minister Herman Haluschenko said.

"Every day since February 24, the world has teetered on the brink of a disaster that will be much worse than Chornobyl and Fukushima combined," he wrote in an address to international organizations and institutions on his Facebook page on Monday.
