Iran's permanent representative to the IAEA Ali Asghar Soltaniyeh said on Tuesday that Tehran will keep on cooperation with the agency.
He also denied Washington's claims that Tehran tries to conceal something about its nuclear exercises and said the US aims at making an anti-Iran atmosphere in the IAEA, reported ISNA.
The US and some western powers which have discussed alleged studies against Iran claim that Iran may have been trying to develop a nuclear warhead and convert uranium to make nuclear arms; Tehran rejecting the allegation insists the program only intends to generate electricity to meet the country's mounting requests.
"The allegations saying Iran is working on nuclear arms are all based on forged and unfounded documents and the issue has been closed before," Soltaniyeh said as adding according to the work plan of Iran and IAEA all "remaining issues" were resolved.
He also called for the normal implementation of the safeguards in Iran.
"If the safeguards be carried out in Iran, Iran like any other country is ready to answer questions, if any," he added.
The IAEA is able to continue verification on Iran's nuclear activities, since Iran has not made any obstacle for the agency to get access to its nuclear materials and facilities, said the representative.
