Three shot dead in Mexico City tourist hotspot, 'mariachi' gunmen fleeAfter 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. In a statement, police said the three victims were killed at an intersection on the edge of Plaza Garibaldi, a major tourist destination packed with mariachi bars, just as the capital was kicking off independence day weekend celebrations. Four of the injured were hurt as the gunmen fled, Mexico City police chief Raymundo Collins told reporters.
