At least 10 people were injured and 15 to 20 people are missing following the event in the province of Narino.
At least 11 people have died in a landslide in Narino province, western Colombia, authorities say, and dozens more have been injured or missing.
The South American Disaster Relief Agency (UNGRD) said on Tuesday evening that the landslide occurred after heavy rains in the rural town of Mallama.
At least 10 people were also injured and between 15 and 20 people are believed to be missing, the agency said.
Two buildings were destroyed in the event.
The director of the UNGRD, Eduardo Jose Gonzalez, had ordered the deployment of a search and rescue team to the site and “he will go early in the morning to the municipality,” the agency said.
However, rescue operations were suspended on Tuesday due to the possibility of further landslides due to rain and were scheduled to resume on Wednesday morning.
Landslides are common in the mountains of Colombia, especially during the rainy season and in areas where precarious informal housing and narrow roads are built on the deforested Andean hills.
In 2017, more than 200 people were killed in mudslides triggered by torrential rains in the town of Mocoa, in neighboring Putumayo province.
