A blast in the southern Russian city of Stavropol that killed at least six people on Wednesday was caused by a self-made explosive device, a top regional investigator said.
An explosive device went off outside the city's House of Culture and Sport early on Wednesday evening before a Chechen band's concert killing at least six and wounding over 42 people.
"According to preliminary information a self-made explosive device went off. It was either remote controlled or equipped with a timer and placed into an empty juice box," Yekaterina Danilova said.
She added that the explosion was equivalent to 0.2-0.3 kg of TNT.
An investigation is underway, and the city's civil defense chief, Boris Skripka, said earlier that criminal proceedings were launched under the articles "murder of two or more persons" and "illegal circulation of explosives." The Investigative Committee said the case also came under the "terrorism" article.
The Stavropol Territory is the largest region in the North Caucasus Federal District, and hosts its administration, but has remained largely free of the violence in the neighboring republics of Chechnya, Ingushetia and Dagestan.
