An explosion deep within Iran’s Fordow nuclear facility has destroyed much of the installation and trapped about 240 personnel deep underground, according to a former intelligence officer of the Islamic regime.

The previously secret nuclear site has become a center for Iran’s nuclear activity because of the 2,700 centrifuges enriching uranium to the 20-percent level. A further enrichment to weapons grade would take only weeks, experts say.

The level of enrichment has been a major concern to Israeli officials, and Prime Minister Benjamin Netanyahu repeatedly has warned about the 20-percent enriched stockpile.

The explosion occurred Monday, the day before Israeli elections weakened Netanyahu’s political control.

[....] According to a source in the security forces protecting Fordow, an explosion on Monday at 11:30 a.m. Tehran time rocked the site, which is buried deep under a mountain and immune not only to airstrikes but to most bunker-buster bombs. The report of the blast came via Hamidreza Zakeri, formerly with the Islamic regime’s Ministry of Intelligence and National Security,

The blast shook facilities within a radius of three miles. Security forces have enforced a no-traffic radius of 15 miles, and the Tehran-Qom highway was shut down for several hours after the blast, the source said. As of Wednesday afternoon, rescue workers had failed to reach the trapped personnel.

The site, about 300 feet under a mountain, had two elevators which now are out of commission. One elevator descended about 240 feet and was used to reach centrifuge chambers. The other went to the bottom to carry heavy equipment and transfer uranium hexafluoride. One emergency staircase reaches the bottom of the site and another one was not complete. The source said the emergency exit southwest of the site is unreachable.

The regime believes the blast was sabotage and the explosives could have reached the area disguised as equipment or in the uranium hexafluoride stock transferred to the site, the source said. The explosion occurred at the third centrifuge chambers, with the high-grade enriched uranium reserves below them.

The information was passed on to U.S. officials but has not been verified or denied by the regime or other sources within the regime.

[....] Several Iranian nuclear scientists have been assassinated in recent years. Last year, saboteurs struck the power supply to the Fordow facility, temporarily disrupting production. And a computer worm called Stuxnet, believed to have originated in the U.S., set Iran’s plans for nuclear weapons back substantially. [....]
