The digital countdown near the Kremlin showed 63 days to kick-off in what is shaping up to be the World Cup of X-ray scanners, metal detectors and surveillance cameras.
Russia is braced for the biggest security operation seen at any modern sporting tournament.
The Luzhniki Stadium which hosts the opening game on June 14 and the final is already in lockdown as workers complete the venue's £350million refit. This includes an iron ring of airport-style security.
Supporters will enter the vast complex through purpose built 'Entrance Pavilions' where they will present their tickets at turnstiles before passing through metal detectors, with all bags put through scanners.
