On Thursday morning, Duque sent two Army battalions and 270 police officers to unblock the Panamerican Highway, which crosses the city and allows vehicles to pass through to Cali.
Videos shared on social networks show a helicopter flying over the area and several protesters being attacked with tear gas canisters.
"The fear and panic are terrible. We have to be locked up at home because we are living in a war. The tear gas is entering through our windows, they are affecting the entire population," recounted Jimena Franco, an inhabitant of the Los Angeles neighborhood.
Local authorities said at least 15 people were injured during the clashes between the Mobile Anti-Riot Squadron (ESMAD), the Army, and protesters.
Police landed a helicopter at an educational center to unload ammunition. "Open the doors. We are the authority," about 30 officers told the school's caretaker, who had refused to let them pass.
"We condemn the landing of troops in our institution. This is a serious human rights violation. No student center should serve as an ammunition depot for the Army to attack civilians," said German Suarez, the center's deputy director.
