VIENNA – The U.N. Security Council plans to meet next week to discuss what to do about Syria’s refusal to cooperate with an investigation of its alleged secret nuclear activities, diplomats told The Associated Press on Monday.

The move comes just weeks after the International Atomic Energy Agency referred it to the council. The closed session could result in anything from debate to sanctions of the kind imposed on Iran for defying international demands to cease activities that could be used to make nuclear arms.

Sanctions are unlikely: Iran continues to expand its nuclear activities in defiance of the council, whereas Syria’s alleged violations appeared to have occurred in the past and thus do not seem to represent a present proliferation threat.

Still, one of the three diplomats who agreed to discuss confidential information on condition of anonymity said the planned July 14 discussions are significant. He pointed to the fact that the council found the issue important enough to take it up less then a month after the June 9 IAEA referral.

The IAEA has tried in vain since 2008 to follow up on strong evidence that a site in the Syrian desert, bombed in 2007 by Israeli warplanes, was a nearly finished reactor built with North Korea’s help.

The resolution that reported Syria to the Security Council expressed “serious concern” over “Syria’s lack of cooperation with the IAEA Director General’s repeated requests for access to additional information and locations as well as Syria’s refusal to engage substantively with the Agency on the nature of the Dair Alzour site.”

Syria is already on the Security Council’s docket. The council on Thursday expressed united support for the U.N. peacekeeping force on the tense Syrian-Israeli border — even while remaining divided over any direct condemnation of Syria’s crackdown on peaceful demonstrators and human rights abuses.

All three diplomats said that the council had asked high-ranking IAEA officials to testify at the hearing — another sign of the importance attached to it. They said that IAEA chief Yukiya Amano and Herman Nackaerts, the agency’s nonproliferation point man, would either both attend or one of them would go.
