Russia not acknowledging breach in INF treaty: US official

The U.S. government will likely announce the suspension of its obligations under the Intermediate-range Nuclear Forces Treaty (INF) with Russia in coming days after bilateral talks failed to make headway, a senior U.S. official told Reuters.

"The Russians still aren't an acknowledgement that they are in violation of the treaty," U.S. Under-Secretary of State for Arms Control and International Security Affairs Andrea Thompson told Reuters in an interview. Thompson added, however, that "diplomacy is never done" and she anticipated more discussions.
