U.N. agency suspects cover-up of nuclear weapons test

The head of the International Atomic Energy Agency said publicly for the first time Monday that the U.N. agency suspects Iran has been cleaning away traces of a 2003 nuclear weapons test ahead of possible inspections of the military facility south of Tehran.

Agency Director Yukiya Amano told the 35-nation board of directors gathered in Vienna that he will meet Iranian officials on Friday to push for his inspectors’ access to the Parchin military complex, according to a text posted on the agency’s website. He expressed concern that evidence of prohibited weapons development activity was being cleaned away.

Amano noted that he had discussed “clarification of issues relating to possible military dimensions to Iran’s nuclear program” during a May 21 visit to Tehran, where he was assured Iran was on the verge of allowing international inspections of its nuclear facilities to resume after a four-year halt.

He urged Iranian officials to sign the agreement worked out during his last visit “as soon as possible” and to provide early access to Parchin.

The International Atomic Energy Agency identified Parchin last year as the site of a suspected test of a nuclear explosives charge. Agency inspectors had visited Parchin in 2005 but didn’t see the area of the suspected detonation chamber because reports of a weapons test blast there hadn’t yet surfaced. The agency’s requests to see the site since then have been denied.

“Information that we have indicates that activities may have been undertaken related to the development of nuclear explosive devices,” Amano said, urging Tehran to allow in inspectors to verify that its activities are exclusively peaceful.

The United States, Israel and other nations have for years speculated that Tehran is secretly working to build nuclear weapons, a charge Iran denies. Tehran insists its nuclear programs are for civilian purposes, such as energy generation and medical research.

Iranian officials met in Baghdad two weeks ago with diplomats from Germany and the five permanent members of the U.N. Security Council — the United States, Russia, China, Britain and France — for talks aimed at ensuring that Tehran’s nuclear developments are free of military applications. No agreements emerged from that forum except to reconvene in Moscow on June 17.
