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.
