Iran confirms centrifuge workshop moved to underground site.

The Islamic regime found a convenient 'excuse' as to why they are inching closer than ever to nuclear capabilities.

Tens of thousands of centrifuges were damaged In the Natanz blast, laments Iranian politician, saying they need highly enriched uranium for submarine propellants and other purposes, including as a bargaining tool.

The Iranian official said the explosion appears to have been an act of sabotage.

Seven ships have caught fire in the latest of a string of explosions in recent weeks in Iran.

A security expert estimates that most of Iran’s main centrifuge assembly hall was destroyed in last week's mysterious explosion at Natanz nuclear facility.

Iran alleges that "enemies" are constantly seeking to destroy its nuclear program and that the Islamic Republic is repeatedly successful in repelling these attacks.

Iran is engaged in negotiations with the West on its nuclear capabilities, but while doing so is developing weapons that would hinder military action against the Islamic Republic.

"We will accelerate the arming of the West Bank, and we think we are entitled to give any response which we deem appropriate," says Iranian military commander.
