U.S. forces conducted a strike in northwest Syria on Friday that resulted in the death of an Al Qaeda affiliate leader who was tied to an ISIS shooter who ambushed and killed Americans last month, officials said. U.S. Central Command said Saturday that the strike killed Bilal Hasan al-Jasim, whom the military described as “an experienced terrorist leader.” Al-Jasim plotted attacks and was directly connected to the shooter in an ISIS ambush in Palmyra, Syria , on Dec. 13, Central Command said in
