Mr. Duque said the presidential helicopter was the “victim of an attack” that took place in the southern region of Catatumbo, on the border with Venezuela.
A video released by the presidency showed several bullet holes in the Colombian air force helicopter.
The right-wing leader said everyone on the plane was safe, including himself and the country’s defense minister and interior minister.
The group was returning from an event titled Peace with Legality, the Sustainable Catatumbo chapter before the incident.
“I want to inform the country that after fulfilling a pledge in Sardinata, in Catatumbo as it approaches the city of Cucuta, the presidential helicopter was the victim of an attack,” the president said in a statement.
He said the helicopter’s equipment and capabilities “prevented something deadly from happening”.
Mr. Duque did not provide the time of the incident or indicate who he said committed it, but several armed groups are known to operate in the area.
The president said the “cowardly” attack would not stop him from fighting drug trafficking, terrorism and organized crime.
“The message is that Colombia is always strong in the face of crime and that our institutions are above any threat,” he added.
