Dutch university students threw eggs, bottles and firecrackers at police as thousands took to the streets of The Hague on Friday to protest against cuts in the education budget, police said.
“Riot and mounted police had to take action to restore order,” police spokesman Wim Hoonhout said.
There were no injuries in the unrest that lasted for about two hours.
Some demonstrators had also dropped a smoke bomb.
Twenty-five arrests were made for vandalism, public violence and maltreatment of bystanders, said a police statement.
Police said 15,000 people, including students and lecturers, took part in the protest in a public park near the city centre, but organizers put the number at more than 20,000.
In a bid to cut spending and reverse a growing public deficit, the government has said it wants to save $501 million US every year from 2012 by making slow learners contribute $2,206 for every year of prolonged study. Tuition normally amounts to $1,250 per year. The higher fee would apply to students who require more than four years to finish a three-year bachelor’s degree and more than two years for a one-year Masters degree, education department spokesman Job Slok said.
