Tens of thousands of students have taken part in protests in Chile in support of education reform.

Organisers said at least 50,000 marched in the capital Santiago on Wednesday, with police saying 25,000 attended.

Chilean students have held a series of mass protests recent months, demanding free public education for all.

Student leaders have said plans expected from conservative President Sebastian Pinera to direct extra money to education are not sufficient.

The protest in Santiago passed off largely peacefully, but some students did clash with police later in the day after a police booth was set on fire.

Smaller protests were also held in other cities, including Valparaiso and Concepcion.

“We will carry on making history… We students will not give up the fight to make education a public right,” student leader Gabriel Boric told Spain’s Efe news agency.
