Two masked men armed opened fire in a bar on the outskirts of the Mexican tourist resort of Cancun on Thursday, killing six people and wounding five, the office of the state's attorney general said.

Public Safety Secretary Jesus Aiza says most of the victims belonged to a taxi drivers union.

Aiza says the assailants arrived at "The Mermaid" bar in a poor area far from Cancun's hotel zone in two cars Thursday afternoon. He says two gunmen using automatic rifles went inside and began shooting.

Aiza says soldiers are guarding the hospital where the wounded are being treated.

Police are still trying to determine a motive for the attack.
