Diplomats attending the International Atomic Energy Agency's (IAEA) meeting said that agency's Director-General, Rafael Grossi, declared that Iran plans to disconnect 20 IAEA surveillance cameras and other monitoring equipment.

This comes after the IAEA's Board of Governors adopted on Wednesday a draft resolution submitted by the US, France, UK, and Germany, criticizing Iran for what they claim were incomplete answers given to the IAEA on uranium traces at "undeclared sites". These claims were quickly refuted by the Head of the Atomic Energy Organization of Iran (AEOI), Mohammad Eslami, who said that Iran has neither secret or unwritten nuclear activities nor unreported nuclear sites.

Russia and China both voted against the anti-Iran resolution.

Before the release of the IAEA report that later led to the US and E3 submitting the draft, Grossi visited "Israel", which raised questions regarding the nature of the visit ahead of the BoG meeting, and led to suspicions regarding the IAEA's impartiality.

The AEOI also released a statement on Wednesday, wherein it announced that Tehran has made the decision to remove two of the IAEA's cameras from a nuclear facility.

Iranian news agency ISNA quoted Thursday an informed source as saying that Iran will speed up the production and installation of new generations of centrifuges, including the IR6, IR4, and IR2M generations.

According to the source, this is only one of a series of procedures to be taken by Iran, adding that the IAEA will be informed of them.

Iran's new move, which Grossi announced, seems to be one of those measures.
