The head of the International Atomic Energy Agency said for the first time that a target destroyed by Israeli warplanes in the Syrian desert in 2007 was the covert site of a future nuclear reactor, countering assertions by Syria that it had no atomic secrets.
Previous reports by the International Atomic Energy Agency have suggested that the structure could have been a nuclear reactor. Thursday's comments by IAEA chief Yukiya Amano were the first time the agency has said so unequivocally.
By aligning Amano with the U.S., which first asserted three years ago that the bombed target was a nuclear reactor, the comments could increase pressure on Syria to stop stonewalling agency requests for more information on its nuclear activities.
Amano spoke during a news conference meant to focus on the Fukushima nuclear disaster after a visit to the Paris-based Organization for Economic Cooperation and Development to discuss clean-up efforts at Japan's tsunami-ravaged nuclear plant.
"The facility that was ... destroyed by Israel was a nuclear reactor under construction," he told a full news conference in response to a question from The Associated Press, repeating to the AP in taped comments afterward: "It was a reactor under construction."
Suggesting that Amano had erred in making the public comments, the IAEA later put out a statement that he "did not say that the IAEA had reached the conclusion that the site was definitely a nuclear reactor."
The rollback reflected previous, more circumspect, IAEA language. In a February report, Amano had said only that features of the bombed structure were "similar to what may be found at nuclear reactor sites."
Israel has never publicly commented on the strike or even acknowledged carrying it out. The U.S. has shared intelligence with the agency that identifies the structure as a nearly completed nuclear reactor that, if finished, would have been able to produce plutonium for the fissile core of nuclear warheads.
Syria denies allegations of any covert nuclear activity or interest in developing nuclear arms. Its refusal to allow IAEA inspectors new access to the bombed Al Kibar desert site past a visit three years ago has heightened suspicions that it had something to hide, along with its decision to level the destroyed structure and later build over it.
Drawing on the 2008 visit by its inspectors, the IAEA determined that the destroyed building's size and structure fit specifications that a reactor would have had. The site also contained graphite and natural uranium particles that could be linked to nuclear activities.
The IAEA is also trying to probe several other sites for possible undeclared nuclear activities linked to the bombed target but Damascus has been uncooperative on most counts, saying that most of the sites are restricted because of their military nature.
