Rescue officials say at least 12 bodies have been recovered from a mudslide in northern Colombia that may have buried another 145.
Torrential rains caused the mudslide that engulfed dozens of homes Sunday outside Colombia's second-largest city, Medellin.
Colombian President Juan Manuel Santos said the unusually heavy rainfalls could leave more than 2 million people homeless. Before Sunday's disaster, heavy rains had killed around 170 people this year in Colombia.
In neighboring Venezuela, driving rains have triggered flooding and cave-ins that have killed 34 people and left an estimated 90,000 people homeless.
Officials blame the downpours on the La Nina weather phenomenon, during which cooler-than-normal water temperatures exist in the Tropical Pacific Ocean.
