A video of the fire shared on social media showed thick black smoke rising into the sky.
Firefighters were quickly able to extinguish the fire, the semi-official ISNA news agency cited the Tabriz fire department spokesman as saying.

Iran has been witnessing multiple explosions and fires around military, nuclear, and industrial facilities since late June.
