Homes buried in Colombia landslide

A rescue operation is under way in the Colombian city of Medellin where a number of homes have been buried under tonnes of mud.

Local people were initially digging for survivors with their bare hands before emergency workers arrived.

The authorities say more than two million people have also been affected by the floods, with many left homeless.

The BBC's Wendy Urquhart reports.
