Here's a link to the AP story on Yahoo. To sum up apparently a blast ripped through a nightclub in a Russian town of about 1 Mil people. Some are already speculating/comparing this to the NJ night club fire in which 30 People died and scores were injured. At Present there is no offical word about the Pyro being stored improperly, or if this, like the NJ fire was a case of one thing leading to another.
