the footnote to an article about UN report on human rights violations in Syria

Only toward the every end of the article, there is this mention in passing: "In addition to listing crimes by forces backing the government of President Bashar al-Assad of Syria, the report cites numerous violations by antigovernment forces in the Sunni-led uprising. Two 15-year-old boys were killed in August when a radical Islamist group’s demands were not met — and video of their killings was posted online. The panel names opposition groups, including the Islamic State of Iraq and Syria and the Nusra Front, which it says committed public killings and crimes against humanity against prisoners in the town of Raqqah. Since May, the report said, armed groups operating in Sunni villages have “routinely abducted and killed” farmers belonging to Mr. Assad’s minority Alawite sect."
