Syria rules out new IAEA visit to bombed site

IAEA experts came back June 25 from a four-day visit, carrying environmental samples from the Al Kibar site hit by Israel in September. Those are now being evaluated but the results might be inconclusive.

Because intelligence suggests that radioactive material had not yet been introduced into the alleged reactor before it was hit by Israel, swipes taken in search of radioactive traces were unlikely to have been of use.

So, the inspectors also looked for minute quantities of graphite, a cooling element in the type of North Korean prototype that was allegedly being built with help from Pyongyang. Such a reactor contains hundreds of tons of graphite, and any major explosion would have sent dust over the immediate area.

But — if the Syrians were interested in a cover-up — they would have scoured the region to bury, wash away and otherwise remove any such traces. And although U.S. intelligence says the reactor was close to completion, it is possible that graphite elements were not yet installed at the time of the Sept. 6 bombing.

Such uncertainties — and IAEA hopes of being able to visit the other suspected sites — dictated the need for a follow-up mission.

More broadly, IAEA experts were looking to put questions to Syrian officials based on the intelligence made available to them alleging years of extensive cooperation between the Syrians and teams of visiting North Korean nuclear officials.

North Korea detonated a nuclear device in 2006 in a test. The North is believed by experts to have produced enough weapons-grade plutonium to make as many as 10 nuclear bombs before agreeing to dismantle its weapons program early last year.

But the diplomats said Syria was strenuously denying any concerted North Korean presence in the country — despite intelligence alleging that the building bombed was a reactor of the type only built by the communist state.

They said Syrian officials described meetings between nuclear officials from Pyongyang and their Syrian counterparts as occasional and informal, despite intelligence information to the contrary.
