Mexico: Gunmen kill 7 in Cancun bar shooting

Members of the Mexican Federal Police patrol the city of Culiacan, a northwestern city in Mexico's Sinaloa state, on May 28, 2008. Ever since former president Felipe Calderon deployed thousands of soldiers and federal police to combat organized crime in 2006, the country has been ravaged by violence.

GUADALAJARA, Mexico – Two gunmen burst into a bar in the popular Mexican resort city of Cancun, killing seven people and injured several others, the Associated Press and Reuters reported.

Most of the victims were members of the taxi drivers union, the AP said. 

Police said they were investigating links between the union and organized crime after the attackers who entered "The Little Mermaid" bar specifically targeted union members meeting there on Thursday, El Universal reported.

Reuters said the men were armed with a machine gun and a handgun.
