The fire in Kangan came just a day after nine people were injured in an explosion on Saturday night at the Sepahan Nargostar chemical and fireworks factory in the city of Shahin Shahr in Iran’s Isfahan Province.
The cause of that blast was said to also be under investigation.
The Sepahan Nargostar factory is a producer of industrial and commercial explosive materials and is under the supervision of the National Security Council, according to IRNA (Islamic Republic News Agency), the official government-controlled news agency. The company produces various types of fireworks and gunpowder, as well as nitrate, sodium, potassium, strontium, calcium, copper and barium, the report said.
The explosion was linked to the shooting down of a drone by Israel near the Jordanian border last week, the report said. Prime Minister Benjamin Netanyahu said it was an Iranian drone sent from either Iraq or Syria. The IDF collected fragments of the destroyed aircraft for further examination.
The news of the fires and the explosions comes just days after Iranian officials reported major progress with world powers in negotiations on renewing the Iran nuclear deal.
Last Thursday, Rouhani said all parties to the talks have agreed to lift “all major sanctions” on Iranian oil, petrochemicals, shipping, insurance and the central bank.
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 some of the incidents.
