Iran ? Iran has boosted its supply and output of reactor-grade nuclear material significantly, according to a quarterly report issued Friday by the United Nations’ arms-control division.

Meanwhile, in Syria, international inspectors reported finding unexplained particles of modified uranium at a lab in Damascus, far from the location of an alleged nuclear site.

The inspectors said they discovered the artificially modified uranium particles in samples taken last year from a facility in the Syrian capital called Miniature Neutron Source Reactor. The report disclosed few other details about the discovery or Syria’s response to the agency’s request for an explanation.

The uranium particles found at the facility “are of a type not included in Syria’s declared inventory of nuclear material,” the report states.
