An electrical substation fire in the Iranian capital Tehran on Sunday, state media reported citing the capital’s fire department spokesman.
Social media users shared videos showing a large, black smoke rising into the sky of Tehran.
Waste materials left over a substation caught fire around 7 p.m. for “unknown reasons,” the Tehran Fire Department spokesman Jalal Maleki told the official IRNA news agency.
Most of the waste materials that caught fire were carton, Maleki said.
