Dissident says Iran has 4,000 centrifuges

Iran has manufactured about 4,000 centrifuges capable of enriching uranium to weapons grade, an exiled Iranian dissident who helped uncover nearly two decades of covert nuclear activity in 2002 said today.

Alireza Jafarzadeh said the centrifuges – which he said were unknown to the UN nuclear watchdog agency – were ready to be installed at Iran’s nuclear facility in Natanz.
