MOSCOW, June 4 (Reuters) - The Kremlin on Tuesday

described allegations by Microsoft ( MSFT ) that Russia has

stepped up an online disinformation campaign taking aim at

France and the upcoming Paris Olympics as "absolute slander".

Microsoft ( MSFT ) said in a blog post published on Sunday that the

campaign, which it said included falsified news websites and a

feature-length documentary film, was specifically designed to

denigrate the reputation of the International Olympic Committee

(IOC) and create the impression that the summer games will be

marred by violence.

Kremlin spokesman Dmitry Peskov said the criticism had no

substance behind it.
