At least 64 people are dead after a fire tore through a shopping center in Siberia Sunday, according to officials.
The mall in Kemerovo was reportedly very busy when the fire started on the fourth floor. That floor housed a theater, skating rink and children's entertainment center.
The blaze reportedly started in the children's entertainment room, which officials say had a "trampoline pool, filled with foam rubber."
The fire wasn't extinguished until early Monday morning.
Officials are launching a criminal investigation into the cause of the fire.
