Russia has not yet notified the United States about exercises of its nuclear forces that Washington expects Moscow to carry out soon, a senior U.S. military official said on Monday.
The United States says Russia will likely carry out test launches of missiles during its annual "Grom" exercises of its strategic nuclear forces, perhaps in just days.
Under the New START Treaty, Russia is obliged to provide advance notification of such missile launches, U.S. officials say. That has yet to come, the U.S. military official said, speaking on condition of anonymity.
