U.S. reviewing whether Russian missile tests violate treaty

WASHINGTON (Reuters) - The United States is reviewing whether Russia's testing of a new ground-launched cruise missile violates a key arms control treaty and has informed NATO about its concerns and discussed them with Moscow, U.S. officials said on Thursday.

The New York Times reported earlier on Thursday that American officials believe Russia began conducting flight tests of the missile as early as 2008, in what could be a violation of a 1987 treaty banning medium-range missiles.
