More than 100 schools across France have been severely damaged during a wave of high school protests that has intensified in recent days, according to the country's education ministry.
The protests have involved blockades and clashes in several cities, with authorities describing some of the unrest as escalating into serious urban violence.
France's education ministry said about 40 headteachers have also been injured during the disturbances. Around 400 schools were reported to be closed on Friday as the protests continued.
Students have raised concerns including overcrowded classrooms, heavy timetables, shortages of teachers and poor conditions in schools. Some demonstrations have become increasingly confrontational, leading to a major police response.
The interior ministry said nearly 3,000 lycée students had been detained since the protests began, including 1,949 on Thursday alone.
The scale of the damage is also creating financial concerns. Authorities in the Auvergne-Rhône-Alpes region have estimated damage from the unrest at about €25 million, while the overall cost across affected areas could reach hundreds of millions of euros.
Education Minister Édouard Geffray has appealed to parents for help as the government faces pressure to restore order and keep students safe.
The protests remain ongoing, with authorities continuing to monitor schools and public areas affected by the unrest.
