CANCUN, Mexico -- A commando of drug gang gunmen on Thursday stormed ashore at a beach on Mexico's resort-studded Caribbean coast in front of luxury hotels and executed two drug dealers from a rival gang.
The dramatic shooting attack sent tourists scrambling for cover at the resort of Puerto Morelos, just south of Cancun.
The two suspected drug dealers killed Thursday had apparently arrived at the beach in front of the Azul Beach Resort and the Hyatt Ziva Cancun, claiming it was now their territory.
"About 15 people arrived on the beach to assassinate two men who had showed up saying they were the new dealers in the area," the head prosecutor of Quintana Roo state, Oscar Montes de Oca, told the Radio Formula.
The killers apparently arrived by boat. There were reports that one tourist had been injured, but state officials did not immediately confirm that.
The shootings were the latest chapter in drug gang violence that has sullied the reputation of Mexico's Caribbean coast as a once-tranquil oasis.
The state police chief wrote in his Twitter account that "There are no seriously injured or kidnapped tourists," but did not say whether there were any non-serious injuries.
Montes de Oca's office said earlier "there was a clash between rival groups of drug dealers on a beach" near the hotels. Several cartels are fighting for the area's lucrative retail drug trade, including the Jalisco cartel and the a gang allied with the Gulf cartel.
Guests at the Hyatt Ziva Cancun posted videos and photos of tourists hiding or nervously milling in the lobby and hallways of hotels during the incident.
Guests at the nearby Azul Beach Resort also posted videos of people taking shelter or gathering in the lobby. An employee who answered the phone at the hotel said the shooting occurred on the beach near the facility.
Rival cartels often kill another gang's street-level dealers in Mexico to eliminate competition and ensure their drugs are sold first. It is not the first time that tourists have been caught in the crossfire of such battles.
The Puerto Morelos shooting comes two weeks after a California travel blogger and a German tourist were killed in a similar shootout in the beach town of Tulum.
A San Jose, California woman born in India, Anjali Ryot, and German citizen Jennifer Henzold were apparently hit by crossfire from the Oct. 20 drug dealers' shootout in Tulum, south of Puerto Morelos.
Three other foreign tourists were wounded in the shooting at a street-side eatery that has some outdoor tables, right off Tulum's main strip. They included two German men and a Dutch woman.
The German Foreign Office issued a travel advisory about the violence, advising its citizens "if you are currently in the Tulum or Playa del Carmen area, do not leave your secured hotel facilities."
The Tulum gunfight also apparently broke out between two groups that operate street-level drug sales in the area, according to prosecutors.
There have been signs that the situation in Quintana Roo state, where all the resorts are located, was out of control months ago. In June, two men were shot to death on the beach in Tulum and a third was wounded.
And in nearby Playa del Carmen, police stage a massive raid in October on the beach town's restaurant-lined Quinta Avenida, detaining 26 suspects - most apparently for drug sales - after a city policewoman was shot to death and locked in the trunk of a car last week. Prosecutors said Friday they have arrested a suspect in that killing.
Crime "has gone up a little with extortion, with drug sales to foreigners and Mexicans," the prosecutors office said about the raid.
The administration of President Andrés Manuel López Obrador has pinned its hopes on the so-called Maya Riviera, where it has announced plans to build an international airport and a stop for the Maya train, which will run in a loop around the Yucatan peninsula.
