The U.N. disarmament chief and the head of Syria's United Nations mission met with Syrian officials last week and reached an agreement to inspect three sites. Investigators have been blocked from independently verifying conflicting reports, by government forces and by rebels seeking an overthrow, of chemical weapons use, the Washington newspaper The Hill reported.
One site to be checked is Khan al-Asai, a suburb of Aleppo, where the United States says government forces used sarin gas against rebels in March. Russia has countered it was the rebels who used chemical weapons there, the newspaper said.
"The mission will travel to Syria as soon as possible to contemporaneously investigate three of the reported incidents," the U.N. statement said.
