Russia says it has compiled a 100-page report detailing what it says is evidence that Syrian rebels, not forces loyal to President Bashar Assad, were behind a deadly sarin gas attack in an Aleppo suburb earlier this year, McClatchy reports. Though the report itself was not released, the statement drew a pointed comparison between what it said was the scientific detail of the report and the far shorter intelligence summaries that the United States, Britain and France have released to justify their assertion that the Syrian government launched chemical weapons against Damascus suburbs on Aug. 21. Reuters reports Secretary of State John Kerry’s public assertions that moderate Syrian opposition groups are growing in influence appear to be at odds with estimates by U.S. and European intelligence sources and nongovernmental experts, who say Islamic extremists remain by far the fiercest and best-organized rebel elements. Meanwhile, Breitbart reports Al Qaeda-linked rebels attacked a Christian village in western Syria for a second day Thursday.
