A large explosion in Johannesburg's business district has raised concerns of a possible second explosion after one person died and 48 others were injured. Videos show a main road split open, with vehicles overturned by the force of the blast. Authorities suspect an underground gas pipe may be responsible and have urged the public to stay away from the area. Emergency services remain on the scene, and people are being evacuated where necessary. Investigations are underway to determine the cause, and local gas supplier Egoli Gas is checking their pipes for possible leaks. Twelve injured individuals are still being treated in hospitals.
