A mother of five, Anna Sobie's wooden home is one of many that has been demolished in a shanty town in a lagoon in Lagos, with critics describing it as a "land-grab" by the authorities to gentrify the prime waterfront spot in Nigeria's biggest city. Lagos State government officials deny the allegation, saying they are demolishing parts of Makoko - the country's biggest informal waterfront settlement - because it is expanding near high voltage power lines, posing a major health and safety risk.
