More than a dozen armed assailants staged and videotaped simultaneous attacks against on two offices of the state attorney general Tuesday in the Pacific resort city of Acapulco, killing at least seven people.

The attacks took place before 11 a.m. in two neighborhoods about nine miles north of the tourist zone, said Enrique Gil Mercado, special prosecutor for the attorney general's office in the state of Guerrero, which includes Acapulco.

Four of the victims, including three agents and a secretary, were killed at an office in the Emiliano Zapata neighborhood, while three, including two agents and a secretary, were killed in the Ciudad del Renacimiento neighborhood, Gil said.

About eight men armed with assault weapons participated in each attack. Gil said he did not immediately know how many people were wounded. He said all the attackers escaped, including one who fled on foot. Authorities initially said city police stations had been attacked, but later revised the information.

Acapulco government official Felipe Kuri Sanchez said the attackers, dressed in military uniforms, entered the offices and that one of them asked, "Are you the only ones here?"

When the officials responded in the affirmative, some of the assailants opened fire while at least one videotaped the shootings in each office, Kuri said.

Following the attacks, other offices were evacuated as a precaution, Formato 21 radio reported.

Police did not comment on the possible motive for the attacks.

Acapulco has suffered a wave of killings as rival drug cartels fight over coastal smuggling routes and control over a burgeoning local drug market.

Last year, the heads of at least six police officers and alleged drug smugglers were found in the resort and nearby towns.

President Felipe Calderon, who took power in December, has sent more than 24,000 federal police and soldiers to regions ravaged by drug violence. More than 7,000 troops arrived in the Acapulco region last month.

Tourists have not been immune from the violence.

On Saturday, two Canadians suffered minor injuries after being grazed by bullets fired at the city's Casa Inn Hotel. The two were treated at a hospital and released. Police have not made any arrests in that case.
