TOPSHOTS Residents of Deep Sea slum in Nairobi use sticks to destroy part of the remaining houses to control the spread of a fire caused by an electrical fault which razed the slum on April 9, 2014. There is a high risk of fire in Nairobi's slums and informal settlements due to the homes being poorly constructed and the materials used of inferior quality. In addition, people live in overcrowded conditions, and electricital connections, where they exist, are often unsafe. AFP PHOTO / SIMON MAINA
