"Accident" At Iran Nuclear Facility A Day After New Deal Breach: Official

The authorities blamed that incident on "sabotage" by "terrorists", but have not released the results of their investigation into it.

An "accident" took place at an Iranian nuclear facility on Sunday but caused no casualties or damage, the Fars news agency reported, citing the spokesman of Iran's nuclear agency. Behrouz Kamalvandi said there had been "an accident in part of the electrical circuit of the (uranium) enrichment facility" at the Natanz complex, a day after Iran announced it had started up advanced uranium enrichment centrifuges at the site in a breach of its undertakings under a troubled 2015 nuclear deal. There were "no casualties nor pollution", he said, adding that "the causes of the accident are under investigation and more details will be released later". The accident follows an explosion at a factory for advanced centrifuges at Natanz last July.
