Fear - inspiring images are published when the attacker in St Petersburg enters the market and leaves his bag with the artisan bomb

It is believed that the explosion in a market that caused the wound of 13 people in St Petersburg was caused by an artisanal bomb in which there were sharp pieces of metal and nails of all kinds.

Russian President Vladimir Putin has named the attack on the market in St. Petersburg as a terrorist attack, with alleging that he has ordered the FSB security agency to bring the law back on the case of the assailant's arrest.

Today a video footage of security cameras has been published, showing the suspected person activating the artisan bomb, entering the market with a bag in his arm.

He first goes into the market in the client's quality, then leaves the bag in a closet and leaves the scene as if nothing bad had happened.

Just 30 minutes later, however, there was an explosion where 13 people were injured.
