Mexican prosecutors say four leaders of violent teachers protests have been arrested on charges of sedition, terrorism, rioting and property damage.

The Attorney General's Office of the southern state of Guerrero says the four have been sent to federal prisons in other states.

The office said Friday that other arrest warrants are pending in the case of protests last month in which demonstrators blocked highways, battled police and trashed the offices of political parties.

The protests are being led by unionized teachers in Guerrero who oppose an educational reform law that will introduce teacher evaluation and reduce the unions' power in hiring decisions.

The teachers are demanding the law be changed, saying a simple test can't be allowed to determine teacher performance.
