1 killed, 6 injured after gunman opens fire at Mexico's pyramids

Six people were injured and a Canadian tourist was killed after a gunman opened fire at Mexico's popular heritage site, the Teotihuacan pyramids. Videos showed the attacker standing atop one of the pyramids and firing at visitors below as people ducked for cover. The attacker later died from a self-inflicted gunshot wound, and a gun, knife, and ammunition were recovered.
