Tens of thousands of students and teachers have marched in the Chilean capital, Santiago, in the latest mass protest to demand educational reform.

智利数以万计的老师和学生在首都圣地亚哥举行了示威游行，要求政府举行教育改革。

Organisers said 180,000 people joined the march
The march was largely peaceful, but ended with clashes between riot police and masked youths throwing stones.

The protest movement - now in its fourth month - is the biggest in Chile since the return to democracy in 1990.

The government has promised some reforms, but the students say they do not go far enough.

Protest organisers said around 180,000 people took part in Thursday's march, making it the biggest in several weeks.

Some wore fancy dress or played musical instruments as they marched through Santiago.

As the march drew to a close, small groups wearing hoods¹（头巾） threw stones at riot police, who responded with tear gas and water canon.

'Apartheid'

Student leaders are demanding wholesale²（批发的，大规模的） reform Chile's education system, which they say is deeply unequal and desperately³ underfunded.

The system is sharply divided between private and public schools, an approach critics have labelled as "educational apartheid".

The protesters want the central government to take full control of education and increase spending on public schools.

They also want increased funding for universities, including scholarships rather than loans for poorer students, and an end to profit in education.

President Sebastian Pinera has responded by promising⁴ limited reforms and around $4 billion (£2.6 billion) in extra funding.
