Ten people were missing and 50 others left trapped after a massive landslide in the northeastern Colombian province of Norte de Santander, authorities said.
The avalanche that struck the hamlet of Teorama was caused by torrential rains, Colombia's emergency management office said.
An army reconnaissance flight confirmed that one residence was buried in the mud and "its 10 inhabitants still remain missing," the office said.
"The only way to reach the impact site is by air," provincial emergency management chief Norela Arenas Valencia said, adding that the army is providing planes to bring in aid and transport search and rescue gear for the Red Cross.
Search efforts had to be suspended due to poor visibility, but were set to resume at first light on Wednesday, Arenas said. EFE
