A landslide at a garbage dump on the outskirts of Ethiopia's capital Addis Ababa has killed at least 24 people, a city spokesman told AFP on Sunday.

The landslide late Saturday levelled more than 30 homes and left 28 people injured, many of whom were squatters scavenging from the Koshe landfill, said Dagmawit Moges, head of the Addis Ababa city communications bureau.
