Rescue workers continue to search the ground to see if more people have been killed in the landslide in the Dosquebradas district of Pereiras in central Colombia.

- We heard a thunder.

When we came out, we saw how part of a mountain ended up on our roofs, Dubernei Hernandez told AFP.

He managed to help dig out a survivor, but also found dead.

Rescue workers fear further landslides as the nearby river and the ponds of Lake Otun are close to the breaking point.
