BREAKING Akhabar Fori channel quotes "Daneshju agency" which it quotes local sources about hearing a HUGE explosion over Natanz. 

The "Daneshju agency" is run by the Basij which are the thugs that do the dirty work of the Iranian Ayatollahs.

The Iranian Fars (Gov controlled)  news agency reports that an unidentified glider is being intercepted in the area of Druid about 20 km from the Bentz underground nuclear facility.

The blast occurred in the area of Badrod (close to Natanz). Iranian security forces are removing civilians from the area.

It should be remembered that even in past cases, the Iranians have tried to obscure the damage caused to nuclear facilities.
We will wait to see what the situation is this time. The information is still preliminary.
