Kremlin accuses the West of helping Ukraine attack Russia

MOSCOW, Aug 16 (Reuters) - An influential aide to Russian President Vladimir Putin said on Friday that the West and the U.S.-led NATO alliance had helped to plan Ukraine's surprise attack on Russia's Kursk region, something Washington has denied.

The lightning incursion, the biggest into Russia by a foreign power since World War Two, began on Aug. 6 when thousands of Ukrainian troops crossed Russia's western border in a major embarrassment for Putin's military.
