At least 101 people died and 140 were injured when fireworks sparked a blaze which led to a stampede in a packed Russian nightclub.Revellers rushed to the exits of the club in the centre of the city of Perm. Early reports suggested there had been an explosion but that is being denied by officials. Regional Minister of Public Security Igor Orlov said: “According to preliminary information from Federal Security Service bomb disposal experts, there was no explosion. Again, the preliminary cause is a fire. There were floodlights inside and so-called ‘cold’ fireworks were used. The stage where the artists performed was equipped with a false ceiling made of inflammable material.” Flames tore through the Lame Horse nightclub in Perm near the Ural mountains, Russia’s sixth largest city, at 11.15 Moscow time on Friday night. Russian TV showed pictures of charred bodies piled on the pavement outside as paramedics carried the injured to waiting ambulances. Investigators say they do not suspect terrorist involvement.
