An Iranian defense industry body said two workers were killed in a fire at an explosives factory in an eastern district of Tehran, the official IRNA news agency reported on Monday.
An Iranian opposition website, Saham, described the incident as a strong explosion and said it took place near Iran’s sprawling Parchin military facility, which is located around 30 kilometers (19 miles) southeast of the capital. It did not give a source for its report, which could not be independently verified.
The UN nuclear watchdog agency suspects Iran around a decade ago may have carried out explosives tests at Parchin that could be relevant for any attempt to develop a nuclear weapons capability. The IAEA wants to visit a specific location at the site, but Iran has so far not granted access.
