A fire broke out at a cellophane factory in northwest Iran on Sunday, the ILNA news agency reported, posting video of thick black smoke rising from the site.

The fire was in the town of Sheikh Hassan in East Azerbaijan province.

There have been several fires and explosions at military, industrial and nuclear sites in Iran since late June.
