By Roberta Rampton WASHINGTON (Reuters) - In another sign of deteriorating relations between the United States and Russia, the U.S. government said on Monday that Moscow had violated the Intermediate Range Nuclear Forces treaty, and urged immediate bilateral talks on the issue. "This is a very serious matter which we have attempted to address with Russia for some time now," an administration official said in a statement. "We encourage Russia to return to compliance with its obligations under the treaty and to eliminate any prohibited items in a verifiable manner," the official said. The official did not describe how Russia violated the treaty.
