Fear spread among hundreds of tourists, who ran in panic, after loud bangs were heard at the Cancun International Airport. Officials sounded a red-alert and flights were grounded for nearly three hours at one of Latin America’s busiest airports. It was a false alarm.

Gunmen opened fire killing 20 people attending a rooster fight in the town of Zinapecuaro, in the western state of Michoacan. It’s a place where rival criminal groups battle each other.  

In Mexico, residents in several states -- including the well-known tourist zones of Cancun -- are expressing deep concerns over rising violence.
