MEXICO CITY—Gunmen with rifles and pistols killed three people on Friday, Sept. 14, and injured at least seven in a tourist plaza in downtown Mexico City, police said, adding that they were chasing three men dressed as mariachi musicians who fled on motorbikes.
After years of keeping a lid on the worst violent crime that has plagued Mexico, its capital has seen homicides surge since 2014 to record levels, presenting a major challenge to an incoming city government that has vowed a clean-up.
