At least 14 people were killed and dozens injured in a landslide after heavy rains in a slum in western Colombia.

"We have 14 dead and 34 injured from this landslide," Pereira City Mayor Carlos Maya said on Tuesday evening.

The authorities had previously reported eleven dead and 35 injured.

Accordingly, a mountain slope had broken off and had buried several houses under it.

The local director of civil protection, Alexander Galindo, spoke to the AFP news agency of two missing people for the time being.

According to initial findings, the landslide is said to be due to "human intervention" in a channel in the upper part of the mountain slope.

According to Galindo, "93,000" millimeters of rain per square meter fell on Monday - "that's how much it rains in Pereira under normal conditions in 20 days".

Villagers and rescue workers helped clear the rubble to search for bodies or survivors, an AFP reporter reported.

The military supported the rescue and recovery work.

The rescue teams also warned of possible further landslides due to flooding in the nearby Otún River.

Dozens of houses were therefore evacuated.
