OAXACA, Mexico -- Thousands of antigovernment demonstrators marched through this tense colonial city yesterday, demanding the security forces abandon camps they set up last week to end a five-month protest.
Masked police officers clutching automatic weapons watched the protesters from rooftops as they marched to a plaza about a block away from the encampments, yelling, "Get out, federal police!"
The leaders then formed a human chain to keep the crowd of 20,000 from confronting police, but about 400 people broke through and attacked the officers with stones and bottles. The forces raised their shields to protect themselves, but did not use tear gas or fire their weapons.
A radio station at Oaxaca's university, where the leftists had set up their base last week, reported that gunmen had fired at some protesters near the university earlier yesterday, injuring a 21-year-old student who was taken to a public hospital.
The hospital confirmed a student had been brought in with a bullet wound. There was no immediate government reaction to the report.
About 4,000 federal police swooped into the city on Oct. 29 to restore order following a five-month protest that had rattled President Vicente Fox's administration, scared tourists out of Oaxaca, and left at least nine people dead, mostly protesters shot by armed gangs.
After being chased out of the city center, the demonstrators moved to the university. Police surrounded the campus last week and battled hundreds of protesters armed with gasoline bombs, stones, and fireworks stuffed with glass and nails, leaving more than 30 people injured.
On Saturday, masked protesters detained and blindfolded two men near the university, accusing them of spying for federal police.
Mexico's Defense Ministry said in a statement yesterday that the men were soldiers who were tied up, beaten, and robbed before being released. The ministry condemned the action but said it maintains its "commitment to the Mexican people" in "staying on the sidelines of the current situation occurring in the capital of the state of Oaxaca."
The protests began in May when teachers went on strike for better pay and conditions in one of Mexico's poorest states. When police broke up one of their demonstrations violently in June, protesters expanded their demands to include the ouster of Governor Ulises Ruiz of Oaxaca, whom they accused of rigging the 2004 election that brought him to power.
Now the demonstrators also want the federal police to leave.
"They don't guarantee security; to the contrary, they scare us and are rude," said Jesus Velasco, 60, a businessman who was marching yesterday.
But the Fox administration says the federal troops are there to restore order. " We see them as part of the solution," Interior Undersecretary Arturo Chavez said.
