A huge fire broke out on Sunday at a home appliances' warehouse in the northeast city of Mashhad in Iran, state media reported.
"Firefighters have been dispatched from different areas of the city," the official news agency IRNA said, without giving further details.
The Mashhad fire department said no casualties had been reported, while dozens of fire fighters were still working to put out the fire, the semi-official Tasnim news agency said.
In March, another large fire broke out at three warehouses of a home appliances manufacturer in the city.
There have been a number of explosions and fires near Iran’s military, nuclear and industrial facilities in recent years.
On January 28, a huge fire erupted at an Iranian military industry factory following a suspected drone strike in the central city of Esfahan.
Iran blamed Israel for the drone attack vowing revenge.
On the same day, another large blaze also engulfed an industrial area near the city of Tabriz, northwest Iran. The government said the fire started at a refinery producing motor oil.
