Blaze engulfs top of Moscow's Federation Tower complex

Russian fire crews have tackled a spectacular fire that engulfed the top of a Moscow skyscraper still under construction.

Helicopters helped douse the flames which broke out more than 60 floors up on the Federation Tower complex.

The fire - visible across the city - was brought under control after about four hours, Russian media said. The cause is not yet clear.
