The training centre next to the Metro Rail Park station in Johannesburg was "burning fiercely" on Sunday morning, Johannesburg emergency medical services said.

Spokeswoman Nana Radebe said emergency services were fighting the blaze on Sunday morning.

There have been no reports of injuries or deaths related to the fire.

The cause of the fire was unknown and an investigation would be launched once the fire had been extinguished, she said.
