KAMPALA, Uganda: A vast landfill site in the Ugandan capital has collapsed, killing at least 18 people, the Red Cross said. Fourteen other people were injured when the Kiteezi landfill, which serves as a waste disposal site for much of Kampala, collapsed late Friday. At least two of the dead were children, Kampala Capital City Authority said in a statement. The collapse is believed to have been triggered by heavy rainfall. The precise details of what happened were unclear, but the city authority said there was a “structural failure in waste mass.”
