The two people aboard were killed when a Canadian-registered small airplane crashed over the weekend in the northeastern province of Santander, Colombia's civil aviation agency said Monday.

"At this time, the announcement is made of the removal of the two occupants of the aircraft, who regrettably perished in the incident," read a communique issued by aviation authorities.

After searching for almost 48 hours, the Colombian air force on Monday spotted the wreckage of the plane "in the Cruz Colorado and Carnicerias uplands in the municipality of Onzaga in Santander (province)."

The aircraft took off from Bucaramanga, the capital of Santander, on Saturday morning but it vanished in a mountainous zone before midday.

Authorities encountered a number of difficulties while trying to locate the accident site, given that this is a mountainous region with peaks rising more than 3,000 meters (9,836 feet) and several hours by foot from the closest spot accessible to vehicles. EFE
