Iran's envoy to the International Atomic Energy Agency (IAEA) Ali-Asghar Soltanieh says the UN nuclear agency has inspected the country's nuclear facilities with an unprecedented drive.
"We have had over 4,000 man-day inspections, the most robust inspection in the history of the IAEA," Iranian Ambassador to the IAEA Ali-Asghar Soltanieh said in an interview with France 24 on Tuesday.
"No country has been inspected the same way as Iran has been," he added.
"And continuously, for the last eight years... there is no evidence of diversion of nuclear material and activities towards military purpose [sic]," Soltanieh explained.
The United States and its allies accuse Iran of following a military nuclear program, but Tehran has repeatedly refuted the charges.
Under Western pressure, the UN Security Council imposed a fourth round of sanctions against Iran's financial and military sectors in June.
In December, IAEA Director General Yukiya Amano released its latest report on Iran's nuclear work, in which he once gain confirmed that the IAEA continued to "verify the non-diversion of declared nuclear material in Iran."
Tehran argues that as a member of the IAEA and a signatory to the Nuclear Non-Proliferation Treaty, the country has the right to use peaceful nuclear energy.
The IAEA, which is tasked with supervising the peaceful use of nuclear energy, was established in 1957.
