United Nations inspectors will visit Iran's recently disclosed nuclear power plant on October 25, the head of the International Atomic Energy Agency announced Sunday from Tehran.

"It is important for us to send out inspectors to do comprehensive verification ... to assure ourselves that it is ... fit for peaceful purposes," Mohamed ElBaradei said.

Iran sent shock waves through the international community recently when Tehran wrote a letter to the IAEA revealing the existence of a nuclear enrichment facility near the city of Qom.

The Islamic republic says its nuclear program is only for peaceful purposes, but the United States, among others, fear the country aims to build nuclear weapons.

ElBaradei urged Iran to submit to more comprehensive inspections because its nuclear program is so advanced.
