A teacher has been stabbed to death in the southern Mexican state of Oaxaca, where demonstrators have been calling on the governor to resign.
Reports from the scene say the man died Thursday and that he opposed a statewide teachers' strike that began several months ago. Protests have become increasingly violent, with at least three dead.
Pro-strike demonstrators accuse Governor Ulises Ruiz of corruption and for months they have called on him to step down. Military aircraft have flown over the demonstrations in recent days, but the Mexican government said Thursday it will not order troops to move against the protesters.
The U.S. State Department has warned citizens against travel in the area.
