According to this CNN update, things aren't all that settled:
Buildings torched, dozens injured in Mexican tourist town
Protesters set fire to another building in the colonial city of Oaxaca on Sunday, after torching government offices and vehicles Saturday in demonstrations that left at least 43 injured and 100 arrested.
On Saturday, leftist protesters demanding the resignation of the Oaxaca state governor hurled rocks, powerful fireworks and gasoline bombs at federal police as they tried to encircle the officers in the picturesque, arch-ringed main square of the city.
