“Members of an American-backed rebel group in Syria beheaded a young child in a grisly execution video. The footage surfaced early Tuesday of members of Harakat Nour al-Din al-Zenki and a captured child in Handarat, near Aleppo. The young boy, who appears to be prepubescent, is then executed on the back of a pickup truck.”
