The information we have is that bodies of 18 people haven’t been found though there is a need for further investigation,” she told reporters in the capital Addis Ababa. Some 500 displaced people were receiving emergency relief aid, she said, adding that efforts were underway to “prevent such types of landslides”.South Ethiopia had been battered by the short seasonal rains between April and early May, which caused flooding and mass displacement.Africa’s second most populous nation is often afflicted by climate-related disasters and more than 21 million people, or about 18 percent of the population, rely on humanitarian aid as a result of conflict, flooding or drought.
