Head of Iran's Parliament National Security and Foreign Policy Commission Alaeddin Boroujerdi on Sunday urged the chief of the International Atomic Energy Agency (IAEA), Yukiya Amano, to reconsider his report on Iran's nuclear activities.

Boroujerdi told reporters that "since Mr. Amano is to present his report to the agency's Board of Governors next Monday, he'd better use the chance and change the report," the official IRNA news agency reported.

In a confidential report which was leaked out on Thursday, the Vienna-based IAEA said it was concerned about possible activities in Iran to develop a nuclear payload for a missile.

The report confirmed Iran had produced its first batch of 20 percent highly enriched uranium, but adding that Iran had failed to give inspectors the required advance notice.

Boroujerdi labelled the report as the most "unrealistic" one which has been yet released by the UN nuclear watchdog, according to the report.

Amano's report is more politicized than technical, he added.

"Iran's latest achievements in 20-percent uranium enrichment have been officially announced to the IAEA and have been made under supervision of the agency's inspectors," Boroujerdi was quoted by the IRNA as saying.

In an effort to rein in Iran's nuclear program, the United States, along with Britain, France and Germany, have been pushing for a fourth round of UN Security Council sanctions.

Iran's Supreme Leader Ayatollah Ali Khamenei reiterated on Friday that Iran does not seek to develop nuclear weapons, according to the IRNA.
