Fire at Zarand Iranian Steel Company, June 6, 2021
An explosion and fire were reported at the Zarand Iranian Steel Company in eastern Iran on Saturday night, in the latest in a series of similar incidents throughout Iran, according to Iranian media.

Video reportedly from the scene showed a large blaze with what appeared to be an explosion launching debris into the air. The Iranian IRNA news reported that a large explosion occurred during the incident.
The governor of Zarand told the Iranian Fars News Agency that no injuries were caused in the incident and that the incident was under control. The incident was reportedly caused by the sudden overflow of molten material in the blast furnace, with the governor stressing that no explosion occurred.
The governor added that firefighters and emergency services were at the scene in order to prevent possible accidents and that more details would be made available later.
The Zarand Iranian Steel Company is part of Middle East Mines and Mineral Industries Development Holding Company (MIDHCO), which was placed under sanctions by the Trump administration earlier this year.
"The Iranian metals sector is an important revenue source for the Iranian regime, generating wealth for its corrupt leaders and financing a range of nefarious activities, including the proliferation of weapons of mass destruction and their means of delivery, support for foreign terrorist groups, and a variety of human rights abuses, at home and abroad," said the US Department of the Treasury at the time.
The fire at the steel plant is the latest in a series of similar incidents that have plagued Iran in recent weeks.
Last week, Iran's largest naval ship, the Kharg training support vessel, sank recently after it was destroyed in a fire. It is unclear what caused the fire.
Additionally, a massive fire was reported at an oil refinery in the southern part of Tehran last week, with no casualties reported in the incident.
Additional fires have been reported at a number of petrochemical plants throughout Iran in recent weeks.
At least one fire has been associated with an Iranian military site, with The Guardian reporting that a blast hit the Iran Aircraft Manufacturing Industrial Company (HESA), which produces a variety of aircraft, including drones, for Iranian and pro-Iranian forces in Iran's Isfahan Province.
Iranian media reported that the blast had occurred at the Sepahan Nargostar chemical and fireworks factory in the city of Shahin Shahr in Isfahan, stating at the time that the cause of the blast was under investigation. The Sepahan Nargostar factory is a producer of industrial and commercial explosive materials.
Last year, a series of explosions and fires hit industrial sites across Iran, including a number of petrochemical plants. Iranian officials referred to most of the cases as incidents or accidents, although some reports have claimed that at least some of them involved foul play. 
Aging infrastructure in Iran has also been blamed for at least some of the incidents.
