Three police shot dead at Mexico City airport THREE federal police officers were shot and killed overnight when they tried to arrest drug trafficking suspects at Mexico City's international airport. Airport spokesman Jorge Andres Gomez said the incident took place around 8:50 am (local time) in the fast-food area of the airport's Terminal 2. The identity and location of the suspects was not immediately clear. "Finding themselves surrounded," the alleged traffickers "opened fire with their weapons against the federal police," the Public Security ministry said. Two federal police officers died at the airport while another died of wounds in the hospital. Federal and local police cordoned off the area and used airport signs to cover the food court windows. People at the busy airport area hit the ground and rushed to hide in the bathrooms when the shooting broke out. At least 14 shots were fired, Milenio TV reported. Some witnesses said that police officers had fired on their colleagues. But at least one witness contradicted that report. "We threw ourselves on the ground - there were four civilians shooting at the police," a female witness who refused to give her name told radio Formato21. Another female witness said it took five to 10 minutes for police reinforcements to arrive. The Ministry of Communications and Transportation issued a brief statement denouncing the "quarrel in an area of open access" of the airport's Terminal 2. Airline operations "are carrying on normally and this situation does not in any way affect operations," the note said, omitting references to any people killed. Police patrols have increased across the country ahead of Sunday's presidential election. Benito Juarez International Airport is located within Mexico City. Terminal 2 opened five years ago, a hub for Aeromexico, Chile's LAN and Panama's Copa Airlines.
