4 Die, 25 Injured in Attack at Cockfight

Assailants threw grenades into a crowded cockfighting ring at a racetrack in Tonala in western Mexico, killing four people and wounding 25, investigators said.

The explosions tossed chairs and sent onlookers fleeing from the scene, which was splattered with blood.

Federal and state authorities were investigating and searching for two attackers.

At a news conference in Guadalajara, the state attorney general refused to comment on reports that the attack had targeted Mexico's Milenio drug cartel.
