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 International Atomic Energy Agency (IAEA) will be informed of them.

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"; claims which were refuted by Head of the Atomic Energy Organization of Iran, Mohammad Eslami who said that Iran has neither secret or unwritten nuclear activities nor unreported nuclear sites.

On Wednesday, Iran's delegate to the International Atomic Energy Agency (IAEA), Mohammad Reza Ghaebi, strongly condemned the decision made by the agency's Board of Governors to adopt the resolution drafted by the US and the E3 that demands more "transparency and cooperation" from Iran.

Ghaebi asserted that this resolution only serves unjust political goals by some of the IAEA members and that the allegations present in the Director-General's report on the locations in question in Iran are based on lies propagated by "Israel".

The Atomic Energy Organization of Iran (AEOI) 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.

The cameras were stopped as they were not part of Iran's commitment to the comprehensive Safeguards agreement.

The Iranian organization's Spokesperson Behrouz Kamalvandi said all beyond-Safeguards cameras recording data in Iran's nuclear sites were turned off “in accordance with the Strategic Law on the Lifting of Sanctions approved by the Majlis (Parliament)."

Kamalvandi further added that "Iran cannot be cooperative while the Agency displays unreasonable behavior. We hope the Agency will come to its senses and respond with cooperation with Iran."

It is noteworthy that the IAEA’s adoption of the resolution comes after a surprising meeting between the Director-General of the Agency, Rafael Mariano Grossi, and the Israeli occupation Prime Minister, Naftali Bennett, in "Tel Aviv" on June 3.
