The landslide was caused by heavy rains in Gofa Zone in the remote south of the country on Monday.
Some people remain unaccounted for after a group of people were covered by mud while they were trying to rescue others.
“We are still searching for the missing,” said Markos Melese, director of the disaster response agency in Gofa Zone.
Photographs showed people digging through the mud with the bare hands, with little sign of emergency services at the scene
