FOUR SUSPECTS ARRESTED AFTER AT LEAST 115 ARE KILLED IN A MOSCOW CONCERT ATTACK SAYS RUSSIA

 At least 115 people were killed and more than 140 injured when gunmen attacked a packed concert venue on the outskirts of Moscow, Russia says

A large fire engulfed the roof of the complex and dramatic video shows panicked concertgoers taking cover as shots and explosions ring out.

Four people directly involved in the Moscow concert hall attack are among 11 detained, Russia's security chief tells President Putin. 

Muscovites are queuing to give blood for those injured and flower tributes have been placed at the scene of the attack

The US says it's credible that the Islamic State group could be behind the attack, after it said the group did it. Russia has not commented.

Russia's security service says the detained suspects were planning to cross the border with Ukraine - Kyiv has described the claim as "absurd"
