Five men were killed in different places in Acapulco, a resort city on Mexico's Pacific coast, the Guerrero state Public Safety Secretariat said.

Two men were gunned down Tuesday on Miguel Aleman avenue a short distance from the Magico Mundo Marino children's entertainment center.

The men were shot dead in broad daylight, the secretariat said.

A man's head was found on a sidewalk in Acapulco's Rodrigo de Triana district and his trunk in a sack.

Two legs suspected of belonging to the victim were left hanging off a bridge on the busy Cuauhtemoc avenue, the secretariat said.

Gunmen killed two other men in areas on the outskirts of Acapulco.

One of the victims was identified as Estado Antonio Vargas, a 32-year-old auxiliary state police officer, the secretariat said.

Acapulco, Guerrero's top tourist destination, has been the scene of multiple drug-related killings in recent days.

The Cartel Independiente de Acapulco has been battling the Comando del Diablo for control of the illegal drug trade in the port city, police said.

The Cartel Independiente de Acapulco was created by former members of the gang led by Edgar Valdez Villarreal, who was known as "La Barbie" and was arrested by the Federal Police on Aug. 30, 2010.

Several close associates of Valdez Villarreal, including Moises Montero Alvarez, who was arrested recently, Carlos Antonio Barragan Hernandez and Benjamin Flores Reyes, who was detained in March, formed the cartel after the arrests of several key members of the organization.

The battles for control of the gangs has ratcheted up the level of violence in Acapulco.

The gang war has been marked by shootouts in the streets and the discovery of mutilated bodies with "narcomessages" in Acapulco and other parts of Guerrero.

The Cartel Independiente de Acapulco and the La Barredora gang, two small criminal organizations that mainly operate locally, were behind most of the murders committed this year in the resort city, the Public Safety Secretariat said earlier this month.

Several other even smaller gangs and some large cartels, which were trying to get a foothold in Acapulco, also contributed to the violence.

The Cartel Independiente de Acapulco beheaded 15 people whose bodies were found on Jan. 8 at the Plaza Sendero shopping center, the secretariat said.

Tourism industry leaders have blamed the drop in visitors to Acapulco on the global economic slowdown, interest in newer destinations like Cancun and the wave of drug-related violence.

The federal government decided recently to turn the Tianguis Turistico, Mexico's largest tourism fair, into an event with rotating venues after being in Acapulco for 24 years.

Some tourism industry watchers interpreted the move as a response to the crime and violence in Acapulco.
