Iranian Foreign Minister Ali Akbar Salehi called for the IAEA to avoid presenting alleged studies as "true", ISNA reported.
"Reports released during the term of Mohammad ElBaradei, former Director General of the International Atomic Energy Agency (IAEA) mentioned that documents given to the agency by Americans were not genuine. How we can be held accountable based on documents which according to the agency are not genuine," Salehi told reporters on Sunday.
He also said the recent report of the IAEA Chief Yukiya Amano on Iran's nuclear work has presented "alleged studies as true" lowering dignity of the institution which according to him should work independently and free from biased approaches.
He then added the recent report is arranged better comparing to previous ones due to some objections came by the Non-Aligned Movement (NAM).
"We hope better reports will be released in future and alleged studies be put aside."
Also Iranian ambassador to the IAEA Ali Asghar Soltanieh said the agency has confirmed again there is no diversion to military purposes in Iranian nuclear program.
"The IAEA has again confirmed for the 26th time that there is no diversion to military purposes in Iran's nuclear work," Soltanieh said.
His remarks came after Amano released his reports on Iran's enrichment program on Friday.
"The agency's supervision on Iran's nuclear activities including uranium enrichment is seen in the whole report," Soltanieh told ISNA.
The IAEA Director General's report is to be discussed in the Board of Governors' next week meeting.
Meanwhile regarding Senegalese cutting of ties with Iran, Salehi said, "the issue is not that much serious."
"Considering Iran's close ties with Senegal, third parties are inserting pressures to harm Iran's relations with good neighboring states. But these pressures will go nowhere."
