Gunmen burst into a bar in a blue-collar neighborhood of the Mexican beach resort of Cancun, killing seven people, including the head of a taxi union, the state prosecutor's office said.
Four men with weapons arrived in a convoy of cars in front of "The Mermaid" bar before entering the place and shooting at a group of people on Thursday, the Quintana Roo state prosecutor's office said. A number of people were wounded.
Six victims died on the spot while another one succumbed to his wounds while being taken to a hospital.
Cancun, the country's most popular tourist destination, has mostly avoided the drug-related violence roiling Mexico since 2006. More than 70,000 people have been killed in the drug war in the past six years.
