Colombians have demonstrated against economic reforms and the killing of civil society leaders, with police using tear gas and stun grenades against stone-throwing protesters as some of the rallies turned violent.
They were the first larger protests to take place since nationwide marches late last year.
Students, teachers, workers, trade unionists and indigenous people rallied in several parts of Bogota on Tuesday.
Unrest erupted in Suba, in the north of the capital, where demonstrators turned over rubbish containers and blocked a road, national broadcaster Canal Uno reported.
Clashes and acts of vandalism were later reported in other areas as well. Several people were injured and at least nine arrested.
The protesters are demanding the cancellation of a tax reform approved late last year that they see as being too favourable to big companies, as well as more protection for civil society leaders.
Hundreds of civil society leaders have been killed since the government signed a peace deal with the guerrilla group FARC in 2016, including nearly 20 this year, according to a figure quoted by Blu Radio.
The assassinations are often carried out by drug traffickers, paramilitary forces or guerrilla groups that have entered areas abandoned by FARC and are seeking control over territory.
Road blocks with burning tyres were reported on Tuesday in Bogota, where bus traffic suffered interruptions.
More than 1000 people attended a pot-banging protest and a concert in the capital's central Bolivar Square, according to broadcaster Caracol. Demonstrations were also held in other cities, including Medellin, Cali and Bucaramanga.
President Ivan Duque said the right to peaceful protest should be respected, while calling for "exemplary punishments" for those engaging in violence.
The protests started with nationwide marches called by trade unions and civil society groups that brought an estimated 250,000 people to the streets on November 21. Smaller protests were staged after that.
Demonstrators have accused Duque's conservative government of trying to weaken the rights of retired people and young employees, and are demanding more funds for education.
The death of young demonstrator Dilan Cruz, who was hit by a bean bag fired by riot police on November 23, sparked nationwide outrage.
