Video said to show alleged Ukrainian attack on Kremlin

STORY: A senior Ukrainian presidential official said Kyiv had nothing to do with the purported incident, the most dramatic accusation Russia has levelled against Ukraine since invading its neighbour more than 14 months ago.

The Kremlin said two drones had been used in the alleged attack on Putin's residence in the walled Kremlin citadel, but had been disabled by electronic defences.
