As total of 131 people who were hurt in the terror attack and more than 500 witnesses have been interviewed," he said at a meeting chaired by Russian President Vladimir Putin.

Then, they proceeded inside Crocus City Hall, firing at people who happened to be nearby, regardless of their gender or age.

"Using gasoline in plastic bottles that they brought on them, they set the premises on fire and left the building at 8:11 p.m. Moscow time," Bastrykin said. "The first investigation results indicate that the terror attack was thoroughly planned."
