Protests have spread to other cities in Mexico. On November 4, Zapatista Subcommander Marcos and supporters blocked the international bridge linking Ciudad Juarez and El Paso, Texas. Maquiladora workers also blocked the international bridge between Matamoros and Brownsville in solidarity with the APPO. Meanwhile, in Chiapas, Zapatistas blocked roads and rebel peasants shut down the international bridge on the Guatemalan border with their bodies.
In a more sinister development, on the morning of November 6 bombs exploded at three high-profile targets in Mexico City: the national headquarters of the PRI, the Federal Electoral Tribunal, which had ruled in favor of Calderon in September, and a branch of a Canadian bank. There was property damage but no casualties. A communique jointly signed by five small guerilla groups active in the mountains of the Mexican south claimed responsibility, saying the action was a response to the repression in Oaxaca and warning the government against using the attacks "as a pretext to generate psychosis in the citizenry and to continue repressing the civil, peaceful organizations and movements."
