Rescue workers resumed their search and rescue efforts on Tuesday, after up to 30 people were buried by a mudslide near the town of Giraldo in northwestern Colombia. Authorities had reported that the strong rainy season caused flooding and made many roads unusable across Colombia in recent weeks. The magnitude of the mudslide was making rescue operations very difficult. Authorities said on Tuesday that the rescue operations may take up to a week. Amateur video shows the slide as it tumbled down, wiping out several homes.
