MEXICO CITY (AP) — A high-sided construction truck and a white SUV pulled into the path of Mexico City’s police chief just as dawn was breaking Friday on the capital’s most iconic boulevard and assailants opened fire with .50-caliber sniper rifles and grenades on his armored vehicle. The cinematic ambush involving two-dozen gunmen left chief Omar Garcia Harfuch wounded with three bullet impacts and shrapnel. Two members of his security detail were killed, as was a woman who happened to be driving by. The high-powered armament and brazenness of the attack suggested the Jalisco New Generation Cartel and hours after the attack, Garcia blamed them via Twitter from the hospital. “This morning we were attacked in a cowardly way by the CJNG, Garcia tweeted, using the Spanish-language acronym for Mexico’s most violent criminal group.
