MOSCOW (Reuters) -Russia's ambassador to the United States on Friday compared the state of U.S.-Russia relations to an "ice age", and said that the risk of a clash between the two countries was "high", Russian state-owned news agency TASS reported.

TASS cited Anatoly Antonov as saying that it was hard to say when talks on strategic dialogue between the two sides could resume, but that talks on prisoner swaps had been "effective" and would continue.
