MOSCOW (Reuters) – Russia's Ministry of Foreign Affairs said on Wednesday the United States had yet to supply any evidence Moscow was a student in breach of an landmark arms control treaty, but claimed it was in a position to keep discussing the problem with Washington.

The America delivered Russia a 60-day ultimatum on Tuesday into the future clean by what Washington says may be a violation of an 1987 nuclear arms control treaty, saying it could be forced to find a six-month strategy of withdrawal if nothing changed.

Maria Zakharova, a spokeswoman for Russia's foreign ministry, told a briefing that the U.S. embassy in Moscow had paid some text on Tuesday evening saying Washington would quit the Intermediate-Range Nuclear Forces (INF) Treaty unless Russia began adhering to it.

"These documents were received for even more processing," said Zakharova. "Within them one more time there have been groundless allegations about our alleged violation with this agreement. We’ve got repeatedly stated that this is often conjecture. No proof (of the alleged violation) may be fond of us."
