The Lockheed Martin-built Hercules C-130 transport plane was carrying 128 people, including 11 Air Force members, 115 army personnel and two national police officers, according to Hugo Alejandro Lopez, head of the nation’s armed forces.

The death toll was nearly double that of the previous figure given by authorities, who continued search and recovery efforts at the site of the deadly crash.

“The accident occurred as the plane was taking off from Puerto Leguizamo, on the border with Peru,” defence minister Pedro Sanchez said on X.

The plane was believed to have suffered an impact near the end of the runway as it was taking off, firefighter Eduardo San Juan Callejas told Caracol, with a wing of the plane later clipping a tree as it was plummeting.

“The crash caused the plane to catch fire and detonate some sort of explosive devices on board,” he added.

Residents of the remote area were the first to pull out survivors, with videos showing men speeding down a dirt road with wounded soldiers on the back of their motorcycles.

Military vehicles later arrived, though authorities said the crash site was difficult to reach, impeding rescue efforts.

Lopez said that 57 of the survivors had been hospitalised, with 30 of them in non-serious condition at a military clinic.
