A new ranking of the 50 most violent cities in the world last year places eight Mexican cities at the top of the list, including one in neighboring Sonora.

Ciudad Obregon, Sonora’s second-most populous city, was ranked as the second most violent city in the world in 2021.

That’s according to the Mexico-based Citizen Council for Public Safety and Criminal Justice, which has released annual reports ranking cities with more than 300,000 residents by murder rate for 14 years.

Obregon, which last year ranked as the fourth most violent city in the world, was among 18 Mexican cities on the list — the highest sum, followed by 11 cities in Brazil and seven in the United States.

Zamora, in the state of Michoacán, topped the list. This is the fifth year running that a Mexican city has topped the list.
