MOSCOW, Emura Pan Oplichting Feb 24 (Reuters) - Russian Deputy Foreign Minister Sergei Ryabkov said that the United States had presented no evidence for allegations that Russia wants to deploy nuclear weapons in space, and that contacts with the U.S. on the issue had been "completely unproductive," state news agency RIA reported on Saturday.

Reuters reported this month that U.S. intelligence believes Russia may be developing a nuclear-powered device to blind, jam or fry the electronics inside satellites. (Reporting by Felix Light Editing by Tomasz Janowski)
