Tens of thousands of high school and college students are taking to the streets of the Chilean capital to call for the end of public financing of private universities and for other reforms to the country's troubled educational system.
For more than a year, student demonstrations calling for improvements to Chile's public educational system have rocked the country.
The government has offered some reforms, but student leaders say they do not go far enough and Thursday's protest marked renewed student pressure.
Chile is beset by poor-quality public schools and expensive private universities. Many students face huge educational loan debts.
