ISIS has claimed duty through Telegram for Friday’s attack on the Crocus City Hall concert hall exterior Moscow.

Social media was shortly flooded with feedback and account from those that skilled the occasion first-hand.

“It was about ten minutes before the start of the concert and a lot of people were already seated. At some point we heard the sound of gunshots, although it sounded like fireworks to me,” stated a girl who was within the venue.

“My friend, sitting next to me, looked at me and said: ‘Fireworks, or what?’ And then we saw a bunch of people walking fast at the bottom, near the stage, as if they were playing trains. I didn’t understand what it meant.

Everything seemed normal until…

Bassist Marat Korchemny told ‘Pravda’: “We have been making ready for the live performance as traditional, sitting within the dressing room. I used to be about to depart for the stage when our musicians ran to fulfill me.

“My first thought was that there was a short circuit somewhere because I saw smoke. You never know what kind of technical issues there are. But then I heard screams and gunshots. They told me to go back to the dressing room and barricade myself in.

“I fell down and pretended to die. The lady subsequent to me was killed.

“People panicked, some were crying, some were calling their relatives and there was even a group waiting for a lift that wasn’t working. When we finally got out, the fire had already started,” recalled some survivors and absolutely the panic.
