Is Iran’s Fordow nuclear facility sabotaged?

So far the only source is Reza Kahlili, and the only venue is WND, which doesn't make the news very reliable, but as far as wishful thinking goes, it sounds good:

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.

If true, the same article sets the next goal:

The regime’s uranium enrichment process takes place at two known sites: the Natanz facility with more than 10,000 centrifuges and Fordow with more than 2,700.

Uhu... so let's wait a bit more.
