At least thirteen people died Sunday in a landslide that dragged away a small bus traveling on the road between Tumaco and Pasto, in the Narino department bordering Ecuador, official sources said Sunday.

"I deeply mourn the death of at least 13 people who were traveling in a public service vehicle on the Tumaco-Pasto highway, which were hit by a landslide," Alejandro Maya, director of the Colombian National Road Safety Agency, wrote on Twitter.

The landslide took place at a place known as La Nariz del Diablo (the Devil's Nose), at kilometer 66 of the road connecting the department's capital city of Pasto and Tumaco.

The rescue agencies, according to local broadcaster Noticias RCN Television, have already recovered ten bodies, including two minors and two women.

The governor of the Narino department, Camilo Romero, told reporters that officials from the risk management office have already moved heavy machines to the site, to clear the road.

The public bus that was dragged away by the landslide left Tuquerres on Sunday morning with one passenger on board and picked up more along the way, so authorities could not establish the exact number of people in the vehicle.

The search and rescue efforts were suspended at night, due to the steep terrain, and will be resumed Monday morning.

The area has been affected by torrential downpours, which make landslides frequent in this part of the country.
