Why is Nigeria demolishing Lagos lagoon slum?

In Nigeria's commercial capital Lagos, authorities have demolished Makoko - the country's biggest informal waterfront settlement. The Lagos state government says some structures built beneath high-tension power lines pose a serious safety risk. But the scale of demolitions has left thousands of residents displaced and families say they were given little warning and no clear relocation plan. And in Sierra Leone, President Julius Maada Bio has announced January 18th as Remembrance Day for victims of the civil war. Between 1991 and 2002 the west African country's military alongside UN peacekeeping troops fought against rebel groups, resulting in the killing of thousands of people and displacement of more than half of Sierra Leone's population at the time.Presenter: Nkechi Ogbonna Producers: Bella Twine, Keikantse Shumba, Chiamaka Dike and Ayuba Iliya Technical Producer: David Nzau Senior Producer: Charles Gitonga Editors: Samuel Murunga and Maryam Abdalla
