Members of the Tanzanian Red Cross removing a victim of the 2013 Dar es Salaam building collapse from the rubble on 29 March. During this accident, in which a 16-storey residential tower collapsed onto a nearby mosque, more than sixty victims were caught inside the rubble; thirty-six, including five children, died. The cause of the accident was determined to be shoddy construction: poor materials were used, and the building was six stories taller than permitted.Photograph: Muhammad Mahdi Karim
