At least 58 people have died and 43 have been injured in a devastating fire in a five-story building in Johannesburg, South Africa, that had been taken over by homeless people. Firefighters are searching the building floor-by-floor and the death toll is expected to rise. Robert Mulaudzi, a spokesman for the emergency services, said he had "never come across something like this" in his 20 years of service. The South African government has promised to provide assistance to those affected by the tragedy.
