Two senior Iranian officials on Sunday denied reports that the country’s Fordo nuclear facility had been rocked by a huge explosion.

Deputy head of the Iranian Atomic Energy Agency Seyyed Shamseddin Barbroudi said there had been no explosion at the facility whatsoever, according to the official Islamic Republic News Agency.

The chairman of the Iranian parliament’s Committee for Foreign Policy and National Security, Alaeddin Boroujerdi, referred to rumors of the blast as “Western-made propaganda” and said they were “baseless lies” meant to impact ongoing talks on Iran’s nuclear program, reported IRNA.

A report published Friday on the website wnd.com claimed that a blast deep within Fordo last Monday “destroyed much of the installation and trapped about 240 personnel deep underground,” citing information from former intelligence officer Hamidreza Zakeri, who it said used to work with the Islamic regime’s Ministry of Intelligence and National Security.

The article claimed the blast “shook facilities within a radius of three miles,” that Iranian security forces had “enforced a no-traffic radius of 15 miles,” that the Tehran-Qom highway was shut down for several hours after the blast, and that, “as of Wednesday afternoon, rescue workers had failed to reach the trapped personnel.” It said US officials were aware of the reported blast.

There was no independent confirmation of the claims. Nonetheless, Israel’s biggest-selling daily Yedioth Ahronoth led its Sunday paper with the report on the alleged blast, which it said might be “the most significant incidence of sabotage in the Iranian nuclear program to date.”

Asked about the explosion on Sunday, Home Front Defense Minister Avi Dichter, a former head of Israel’s Shin Bet security service, said, “Any explosion in Iran that doesn’t hurt people but hurts its assets is welcome.” Dichter was acting defense minister Sunday, in the absence of Ehud Barak.

Iran insists its nuclear program is for peaceful purposes, but that claim has been rejected by much of the international community. The Islamic Republic’s consistent refusal to allow international inspectors into the Fordo nuclear facility has frustrated Western powers and officials at the International Atomic Energy Agency.
