Iran has started injecting gas into 1,044 centrifuges in Fordow nuclear plant, the country’s nuclear authority said Saturday.  

Behrouz Kamalvandi, a spokesman for the Atomic Energy Organization of Iran (AEOI), said the gas injection in Fordow, 20 miles (32 kilometers) northeast of the city of Qom, was taken upon orders from Iranian President Hassan Rouhani, according to the official IRNA news agency.  

“The machines are now active and have already yielded product,” he said, adding that samples have been taken from the products and the AEOI has asked the UN nuclear watchdog IAEA to dispatch experts to examine them.
