Teachers incensed by sweeping education reforms have attacked the buildings of political parties in Mexico's south-western Guerrero state.
For several hours, masked protesters started fires and attacked the offices with pickaxes and sticks, spraying slogans on the walls.
The state governor has called for support from the federal government.
The reforms impose centralised teacher assessment and seek to end corrupt practices in the education system.
Those practices include the buying and selling of teaching positions.
