At least 63 people were killed and 43 injured on Thursday in a fire in the central business district of South Africa's biggest city of Johannesburg, the municipal government said.
Search and rescue efforts were going on, the city administration said on the platform X, formerly known as Twitter.
"The City of Johannesburg Emergency Management Services can confirm that the number of fatalities has gone up to 63," it said.
Firefighters and emergency vehicles were at the scene, while bodies lay covered in emergency blankets on a street near the site of the early morning blaze, Reuters photographs showed.
Media said the fire engulfed a five-story building that had been abandoned at one stage but where people had been living. It was not immediately clear what caused the fire.
