ACAPULCO, Mexico -- Mexican authorities say seven people were killed in a shootout between rival drug gangs in the Pacific resort city of Acapulco.
Guerrero state investigative police director Fernando Monreal says gunmen used grenades and automatic rifles to attack a house in a residential area of Acapulco on Thursday.
The state of Guerrero, where Acapulco is located, has become a drug cartel battleground.
Authorities on Wednesday found the decapitated bodies of two men inside a car abandoned in the community of Kilometro 30, near Acapulco.
Nationwide, more than 28,000 people have died in drug violence since December 2006, when President Felipe Calderon launched a crackdown against drug traffickers.
