Mexico City airport shooting kills 3 police officers

Drug-trafficking suspects opened fire in a crowded food court at Mexico City's international airport on Monday, killing three federal policemen who were on an anti-narcotics mission as panicked witnesses dove for cover.

A witness said the shooters also wore police uniforms, and the federal Public Safety Department said it was investigating whether the attackers were active-duty police, former officers or impostors.

The slain agents had gone to the airport "to detain suspects linked to drug trafficking at Terminal 2," the Department said in a statement. "Upon seeing themselves surrounded by federal police, they (the suspects) opened fire on the officers."

Two officers died at the scene and another died later of his wounds at a local hospital.
