Gunmen kill 20 at illegal cockfight in Mexico

Gunmen burst into a clandestine cockfight and opened fire, killing 20 people and wounding six, prosecutors in Mexico's western state of Michoacan said. Three women were among the dead after the attack late Sunday.

Prosecutors said drug cartels and other criminal gangs had been fighting in the area. It added that a team of federal investigators had been sent to the scene.

The fighting has included the use of bomb-dropping drones, landmines and home-made armored cars. Cockfighting, while illegal in many areas, remains a popular pastime in parts of Mexico.
