No one has claimed responsibility for the explosion at a branch of the Perekrestok supermarket chain in the city's northwest Kalininsky district. Alexander Klaus, the chief of the local branch of the Investigative Committee, said 10 people were hospitalized with injuries.
Andrey Kibitov, a spokesman for St. Petersburg's governor, tweeted that the injured were in satisfactory condition and one had been discharged from the hospital. A criminal investigation was launched.
While officials stopped short of branding the explosion as a terror attack, the National Anti-Terrorism Committee that oversees anti-terror efforts in Russia said it was coordinating the search for suspects. Sky more
