WASHINGTON, Oct. 6 (UPI) -- A fire broke out in the vicinity of Iran's Parchin military complex and killed two workers in an explosive materials production unit.
The White House said Monday it is "monitoring the situation closely."
The U.S. is among a group involved in nuclear negotiations with Iran. There has been suspicion that the Parchin complex has been used to test explosives in support of Iran's nuclear weapons research. Iran has maintained the Parchin facility is used only for conventional weapons.
"We are aware of reports of an explosion at or near the Parchin military facility in Iran," said National Security Council spokesperson Bernadette Meehan. "We are also aware of reports that Iranian authorities have described the incident as a fire at an explosive materials production unit and that two workers have lost their lives."
