(AP) Teachers angry over the passage of a national education reform are partially blocking the main approach to Mexico City's airport, forcing many passengers to leave their cars and rush through the streets on foot to catch their flights.
Hundreds of police are guarding the airport to prevent the members of a dissident teachers' union from blocking other entrances. Airport management is advising passengers to take alternate routes to the airport, including the subway.
The blockage has traffic backed up for miles (kilometers) on one of the city's main highways, increasing simmering public anger at the weeks of teacher protests.
The teachers, mainly from poor southern states, are protesting a just-approved measure that could break union control over the public education system.
