WASHINGTON — The U.S. government Sunday added weight to its allegations that Russia is deeply involved in the battles in Eastern Ukraine, releasing evidence on Sunday of Russia shelling eastern Ukraine from across the border and of separatists in the area using heavy weapons provided by Russia against the Ukrainian military.
