There were new protests Monday in the Mexican town of Oaxaca, where thousands of people took to the streets to express their anger over violent clashes between federal police and striking teachers and their supporters.
The teachers and other protesters had occupied streets and buildings in Oaxaca for five months.
Mexican government forces moved in after paramilitary forces, allegedly allied to local police, killed an American activist journalist and two others on Friday.
Before this weekend, both sides had shown restraint. On Sunday, a few soldiers were wounded by Molotov cocktails. Protestors say one person was killed, although the government denies it.
The conflict in Oaxaca began with a peaceful teachers' strike to ask for more money. After the governor tried to violently remove them, it evolved into a broad movement -- branded as the Oaxaca People's Popular Assembly, or APPO.
The APPO has had control of Oaxaca for months, holding the city through a web of barricades. Police were chased out and vigilante justice was applied, often harshly.
Protesters have been demanding the ouster of Governor Ulysis Ruiz.
At least eight people, mostly activists, have been killed so far by shadowy paramilitary forces allegedly allied to Ruiz. On Friday, three people were shot dead, including an American journalist.
Those killings prompting the federal troop deployment.
