This week, Moscow's top general has claimed that Russia has tested a low-flying experimental nuclear-powered cruise missile. It is said to be powered by a nuclear reactor and is capable of carrying a nuclear warhead with a potentially unlimited range.

Russia calls it Burevestnik, Nato have codenamed it 鈥楽kyfall鈥�, and others have said it鈥檚 a 鈥榯iny flying Chernobyl鈥�. Western experts have previously cast doubt over missile's strategic value and Russian claims of having successfully tested it.

But how dangerous is it?
