Iran builds new centrifuge rotor factory, says country's nuclear chief

The factory would have the capacity to build rotors for up to 60 IR-6 centrifuges per day

Iran has built a factory that can produce rotors for up to 60 centrifuges a day, the head of its atomic agency said on Wednesday, upping the stakes in a confrontation with Washington over the Islamic Republic's nuclear work.

The announcement came a month after Supreme Leader Ayatollah Ali Khamenei said he had ordered agencies to prepare to increase uranium enrichment capacity if a nuclear deal with world powers falls apart after Washington's withdrawal from the pact.

Under the terms of the 2015 agreement, which was also signed by Russia, China, Britain, France and Germany, Iran agreed to curb its nuclear programme
