Police in Mexico have raided three teachers' colleges in the western state of Michoacan after more than a week of protests against curriculum changes.

Officers arrested at least 120 people as they stormed the schools, where students were holding buses and delivery trucks that they had seized.

Several vehicles, including patrol cars, were set on fire in Monday's violence.
