Russia holds day of mourning after deadly concert shooting in Moscow

Dozens have visited the site of the shooting in Moscow to pay their respects, as ITV News Correspondent Neil Connery reports

Russians observed a day of national mourning on Sunday after a mass shooting at a concert in Moscow which killed more than 130 people.

Some friends and families of those who attended the Crocus City Hall on Friday evening are awaiting news of their whereabouts.

An affiliate of the so-called Islamic State group, which claims responsibility for the attack, has now released graphic footage of what is says are its attackers entering the concert hall.

Four alleged attackers were charged with committing terror offences in a Russian district court on Sunday evening and, if found guilty, could face up to life imprisonment.

The men, who are all citizens of Tajikistan, appeared in court heavily bruised with swollen faces. They have been ordered to be held in pre-trial custody until May 22.

As rescuers continue to search the damaged building, there are fears the death toll could rise further, with some families still unsure if their loved ones are alive.

A steady stream of people have brought flowers and candles to a makeshift memorial near the burnt-out shell of the concert hall.

The Moscow Region's Emergency Situations Ministry posted a video on Sunday, showing construction equipment dismantling the damaged music venue to give rescuers access.

Russian President Vladimir Putin appears to be blaming the attack on Ukraine, despite the Islamic State group's claims.

Putin has called the attack a "bloody, barbaric terrorist act" and said Russian authorities captured four suspects as they were trying to escape to Ukraine through a "window" prepared for them on the Ukrainian side of the border.

A further seven people were arrested on suspicion of helping to coordinate the attack.

Ukraine has denied any involvement, with the United States placing blame solely with Islamic State.

Footage released by Russia's Investigative Committee showed the suspected attackers being dragged while blindfolded into the state body's headquarters in Moscow.

The US shared information with Russia in early March about a planned terrorist attack in Moscow, and issued a public warning to Americans in Russia, according to a National Security Council spokeswoman.

In the West, the attack has been seen as a major embarrassment for the Russian leader, and happened just days after Putin was re-elected president.

Islamic State, which fought against Russia during its intervention in the Syrian civil war, has long targeted the country.

In a statement posted by the group's Aamaq news agency, the Islamic State's Afghanistan affiliate said that it had attacked a large gathering of "Christians" in Krasnogorsk.

The group issued a new statement on Saturday via Aamaq, saying the attackers fired indiscriminately at concertgoers, casting the raid as part of the Islamic State group's ongoing war with countries that it says are fighting against Islam.
