Watch live: Mourners lay flowers outside Russian concert venue where 133 killed in massacre

Mourners are laying flowers outside the Russian concert hall venue where a terrorist attack killed at least 133, and injured many others.

The attack, which took place at Crocus City Hall, in a north-west suburb of Krasnogorsk, is Russia’s deadliest for a number of years. After Russia initially blamed Ukraine, Islamic State have since claimed responsibility. The US say that had previously warned of IS plotting an attack in the country.

It’s thought more than 6,000 people were in the building at the time, getting ready to watch rock group, Picnic, when five men broke in.

Those at the scene have described shots being fired, and ‘petrol bombs’ being thrown, causing a fire.

While the fire is now under control, Russia says that helicopters were brought in to tackle the 12,900-metre blaze.

The attackers have not yet been found.
