What were the Syrians up to?

I read

"The U.N nuclear agency on Friday reported its second unexplained find of uranium particles at a Syrian nuclear site, in a probe sparked by suspicions that a remote desert site hit by Israeli warplanes was a nearly finished plutonium producing reactor.... "In order for the agency to complete its assessment, Syria needs to be more cooperative and transparent," said the IAEA in a document that detailed repeated attempts by agency inspectors to press for renewed inspections and documents — all turned down by Damascus.... On Syria, the agency said the newest traces of uranium were found after months of analysis in environmental samples taken last year of a small experimental reactor in Damascus. It already reported a similar finding in February at a separate site — at or near the building bombed by Israel more than two years ago. As in the case of the earlier find, the uranium particles "are of a type not included in Syria's declared inventory of nuclear material," said the report, saying their origin and potential significance still "needs to be understood." It also said Syria continued to deny cooperation with North Korea in building its nuclear program."

Why does none of the major news organisations cover this story? Why does the UN all but ignore the issue of Syria's nuclear plans? Why is Syria given an all but free-ride whilst pressure is endlessly put on Israel?
