CNN says that the IAEA now wishes to investigate these claims for itself:
[Mr.] ElBaradei said the agency has been discussing the matter with Syrian authorities since it learned of the allegations in April, eight months after the Israeli strike.
The purpose of the talks, ElBaradei said, was to arrange "a visit to Syria at an early date to verify, to the extent possible at this stage, the veracity of the information available to the agency.
"Syria, like all states with comprehensive safeguards agreements, has an obligation to report the planning and construction of any nuclear facility to the agency," the IAEA chief said.
According to The Washington Post, the US government is pushing for the IAEA to enter Syria with a wider assignment, suspecting the existence of several other nuclear facilities:
The Bush administration is pressing U.N. inspectors to broaden their search for possible secret nuclear facilities in Syria, hinting that Damascus's nuclear program might be bigger than the single alleged reactor destroyed by Israeli warplanes last year.
At least three sites have been identified by U.S. officials and passed along to the International Atomic Energy Agency, which is negotiating with Syria for permission to conduct inspections in the country, according to U.S. government officials and Western diplomats. U.S. officials want to know if the suspect sites may have been support facilities for the alleged Al Kibar reactor destroyed in an Israeli air raid Sept. 6, the sources said.
