A senior Iranian official says head of the International Atomic Energy Agency (IAEA) Rafael Grossi's admission of Israeli nuclear weapons tasks him and the agency with a heavy responsibility. 

Iran rejects the latest allegations about its peaceful nuclear program by three European countries, saying it will give an appropriate response to any confrontational move.

Iran says it does not hesitate to respond to unconstructive measures targeting its nuclear program, but is still prepared to continue constructive cooperation with the IAEA.

The spokesman for Iran’s Foreign Ministry has emphasized that the country’s peaceful nuclear program is “fully transparent” and conducted under the continuous monitoring of the UN nuclear agency.

Tehran has dismissed anti-Iran allegations made by the Persian Gulf Cooperation Council (GCC), saying outsiders pose a real danger to regional security and stability.

Foreign Minister Abbas Araghchi has warned about an ongoing debate in Iran over whether to change the nuclear doctrine in the face of the West's continued sanctions on the Islamic Republic.  

Iran says it has injecting uranium gas into its advanced centrifuges following a recent IAEA resolution.
