"It is unacceptable that Iran will begin to pump 1,044 centrifuges at a facility in Fordo today," RIA Novosti quoted Maas as saying.

He stated that this decision "does not comply with Iran’s obligations under the nuclear agreement." According to the minister, Iran "thus puts the deal at stake."

On November 5, Iran handed a letter to the IAEA stating that gas filling of centrifuges at a nuclear facility in Fordo will begin on November 6. Later, he began to supply gas to centrifuges at the facility in Fordo.
