Clashes broke out between student protesters and the police by the District University in Bogota, on the second consecutive day of a national strike, on Friday.
Footage shows police firing water cannon and tear gas at the protesters, who were seen throwing projectiles.
Several demonstrators, some of them injured, were detained.
The strike has been called against a backdrop of rising violence against teachers and social leaders, with teachers also demanding the government stick to agreements to increase education funding as well as improving benefits for educators.
The protesters called on Colombian President Ivan Duque’s government to honour previous agreements with Thursday’s action preceding a general strike called for by unions and student organisations for 25 March, 2020.
The country’s largest teachers’ union, the Colombian Federation of Education Workers (FECODE) stated that up to 300,000 educators throughout the country are participating in the strike – affecting classes for seven million students.
