A shooting erupted at a food court in Mexico City's international airport on Monday and officials said two policemen were killed. According to AP, a witness said the shooters were also disguised in police uniforms. The shootings occurred at the airport's Terminal 2, near the area where vehicles drop off passengers. Three shots rang out at first, said a 23-year-old Mexico City student who had gone to the airport to see off a friend. He didn't see who those first shots were directed at, but then the gunfire came closer.
