CCTV footage of a deadly landslide that killed at least 29 people in the Philippines has emerged.

The video, which is filmed off the screen of a CCTV monitor, shows the moment the side of a mountain near the city of Naga begins to crumble, burying villages and homes below.

Philippine troops and police forcibly evacuated five villages vulnerable to landslides after the collapse of the mountainside.

Some residents left on their own, but most of the more than 1,200 people in villages near the landslide-hit area in Naga city were forcibly moved by authorities Thursday night, police Chief Superintendent Debold Sinas said Friday.
