TEHRAN (Dispatches) -- An investigation has been launched after a massive fire broke out at a dairy factory in Eslamshahr southwest of Tehran.
Authorities said the fire did not cause any casualties.
"There are no casualties ... firefighters have been dispatched to the factory in the Islamshahr county. Efforts to control and extinguish the widespread fire continue,” a fire department official said, adding a probe was launched into the cause of the fire.
Multiple videos showed the blaze engulfing a two-story facility and firefighters trying to douse it with water. A clip uploaded on Twitter by a user showed clouds of thick black smoke rising above the facility engulfed in flames.
The Iranian government said on Tuesday there are strong suspicions that "internal agents” played a role in a massive explosion that occurred at a key nuclear facility earlier this year.
On July 2, a fire ripped through a building at Natanz, a major uranium enrichment site. Images showed it caused the roof to collapse and parts of the building were blackened by the blaze.
"One of the strong theories is based on internal agents being involved in the incident,” Government spokesman Ali Rabiei told reporters at a news conference.
"The issue is being seriously reviewed by the country’s security organizations and we will announce the results after things are clear.”
In late August, Iran’s Atomic Energy Organization confirmed the damage to the facility was the result of "sabotage”.
"But how this explosion took place and with what materials … will be announced by security officials in due course,” spokesman Behrouz Kamalvandi said at the time, citing "security reasons” for not disclosing further information.
Rabiei on Tuesday reiterated that "sabotage is certain” but the incident still needs to be investigated due to its complexities.
The desert Natanz site, much of which is underground, is one of several Iranian facilities regularly monitored by inspectors from the International Atomic Energy Agency (IAEA).
