Large blaze rages at Russian concert hall hit by terrorist attack (VIDEOS)

Multiple fire brigades and aircraft have been deployed to put out a blaze at a large concert hall outside Moscow that was attacked by terrorists on Friday night. The popular shopping center and music venue is located in Krasnogorsk, just northwest of the Russian capital. 

A group of gunmen stormed the Crocus City Hall on Friday night, killing at least 60 people, according to the authorities.

The assailants reportedly set the building on fire. Witnesses also said they heard explosions inside the venue.

According to regional emergency services, around 100 people have been evacuated from the underground floor. The rescuers are working to evacuate people from the roof.

More than 320 firefighters are on site, officials said. Three helicopters are dropping water on the blaze.

Opened in 2009, the Crocus City Hall is a bustling shopping and entertainment hub, which hosts many high-end stores and a music venue. The rock band Picnic was set to perform there on Friday night, so the building was packed with fans at the time of the attack.
