GROUPS of demonstrators were dispersed by tear gas Saturday during a third day of protests in Colombia and videos on social media showed at least one gravely injured protester.

The demonstrations followed an overnight curfew and isolated looting in the capital Bogota.

More than 250,000 people marched in a national strike Thursday to express growing discontent with President Ivan Duque’s government, while thousands gathered Friday for dozens of “cacerolazo” demonstrations — a traditional Latin American protest in which people bang pots and pans.

Three people were killed following Thursday’s protests in connection with alleged looting, which is under investigation by authorities.

Demonstrators’ grievances range from anger at economic plans the government denies supporting to what protesters say is a lack of action to stop corruption and the murder of human rights activists, among other issues.

“I’m against the repression, abuse, aggression and mistreatment that the government is committing,” said pensioner Claudia Rojas, 55, as she gathered at a cacerolazo in Bogota’s Hippie Park among a mostly young crowd while a helicopter circled overhead. “More than anything I’m against the labor, pension and health reforms the government wants.”

The hundreds of demonstrators later sang the national anthem.

Earlier on Saturday hundreds of protesters were dispersed with tear gas from a main roadway near Bogota’s National Park.

Videos posted on social media showed medics performing CPR on one protester, as they kneeled near what appeared to be blood.

Demonstrators also gathered outside of congress in Bolivar Plaza, near the presidential palace. Though vocal, the crowds appeared smaller than previous protests, according to witnesses.

All of Bogota was under curfew from 9 p.m. Friday through 5 a.m. Saturday.

Duque said Saturday the police and army would make continual patrols to prevent further vandalism, after two nights of disturbances left dozens of mass transit stations damaged, several stores looted and many residents panicked about safety.

Bogota Mayor Enrique Penalosa said that looting and what officials said were false reports of residential break-ins overnight may have been coordinated by criminals. “We need to be prepared for a long effort, I invite you to have patience, to have resilience because hard and difficult days are coming,” Penalosa said in a joint news conference with Duque and security officials.(SD-Agencies)
