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

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

The gunmen were dressed in military uniforms and pretended to be conducting a weapons check, said Erit Montufar, director-general of the attorney general’s investigative police offices in Guerrero.

Montufar said an assailant in one office asked: “Are you the only ones here?” At the other office, a gunmen asked: “Are these all the weapons you have?”

The officers answered “yes” to both questions and handed over their weapons. The gunmen then opened fire while videotaping both shootings, Montufar said, citing witness accounts.
