A senior Iranian nuclear official slams the head of the International Atomic Energy Agency (IAEA) for renewing claims about “undeclared” nuclear sites in Iran, saying Tehran has already had “maximum cooperation” with the UN nuclear watchdog to help resolve the situation.

The AEOI spokesman says IAEA’s demands from Iran are “excessive”, adding that they cannot be implemented them due to sanctions.

Iran's nuclear chief Mohammad Eslami says Israel is planning a psychological warfare against the country's nuclear program, calling on IAEA's head to abandon its Israeli-influenced approach.

The AEOI chief says the West has always sought to prevent the country from producing nuclear fuel and having scientific power.

Iran’s nuclear chief says the country began to feed gas into advanced centrifuges in order to show its iron will to fight the sanctions.

Iran says it has enriched uranium to a purity of 20-percent, using a cascade of advanced centrifuges it launched two weeks ago.

The spokesperson for Iran’s nuclear agency says Tehran is mulling over “additional measures” after turning off the International Atomic Energy Agency’s (IAEA) surveillance cameras that functioned beyond the safeguards agreement.
