The cause of the fire was not immediately clear but the province's chief justice Esmail Sadeghi had opened an investigation, Mizan said, noting the centre's capacity was for 40 people.
Sadeghi said several suspects had already been arrested including the centre's manager.
Footage of the fire broadcast by ISNA showed it lighting up the night sky and sending huge plumes of smoke into the air.
Other footage showed emergency personnel, firefighters and ambulances gathered outside the heavily-damage site after the fire was contained, with images showing the centre's roof had been destroyed, its windows shattered and its walls blackened by smoke.
In August, a fire broke out in Tehran's Grand Bazaar, damaging multiple shops but causing no casualties.
In January 2017, a fire at the 15-storey Plasco shopping centre in Tehran, killed at least 22 people, including 16 firefighters.
