The US government will likely announce the suspension of its obligations under the Intermediate-range Nuclear Forces Treaty (INF) with Russia in coming days.
The news comes after bilateral talks failed to make headway, a senior US official told Reuters.
"The Russians still aren't in acknowledgement that they are in violation of the treaty," US 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.
