Iran's ambassador to the International Atomic Energy Agency Ali Asghar Soltaniyeh rejected unfounded claims made by the US and some European countries on Iran's nuclear program.

A letter written by the Iranian official says IAEA regular monitoring of Iran's nuclear facilities and its dispatching of watchdogs proved the US and Europe allegations wrong.

Iran intends to use civilian nuclear technology only to meet the country's growing need for power.

According to Iran's obligations in the Safeguards Agreement, Iran did not had to inform the IAEA of its under construction nuclear facilities 180 days before the facilities receive nuclear materials.

The same thing is true about Iran's Natanz nuclear facilities since the site had not received nuclear materials when was visited by the IAEA director general ElBaradei, he said.

Iran was not to declare its nuclear activities before the determined 180 days since Tehran was not an Additional Protocol member, he said.

Iran has always obeyed Non-Proliferation Treaty rules and never changed his way, Soltaniyeh said.

Meanwhile concerning the issue of contamination, the Iranian representative said Iran was given some time to prove the contamination was due to an external source but not because of enrichment works.

Through Iran's full cooperation during June 2004 the IAEA declared the contamination was not resulted from Iran's enriching activities, Soltaniyeh said.

"Iran continuing nuclear works under NPT framework frustrated US efforts which thought referring Iran's nuclear dossier to the Security Council can exert more pressures on Iran."

According to IAEA charter if inspectors getting access to confidential information and interviews inform the agency of one country's non-obligation to NPT, the director general can deliver the country's case to the Security Council, where as none of the inspectors have seen any diversion in Iran's nuclear program, the Iranian ambassador said.

"Discussing Iran's nuclear dossier in the Security Council organized by the US and some European countries only seeks political purposes."
