The Kremlin said on Tuesday that Russia had not abandoned a moratorium on nuclear testing, and dismissed a suggestion by one commentator that it should detonate a thermonuclear bomb.
Spokesman Dmitry Peskov said he did not know where New York Times reporters had got the idea that Russia may be preparing to test an experimental nuclear-powered cruise missile, or may have recently tested one.
Margarita Simonyan, hawkish editor-in-chief of the state-owned broadcaster RT, suggested in an interview extract posted online by the foreign-based digital broadcast network RTVI that Russia should detonate a nuclear bomb at high altitude over Siberia as a warning to the West.
