One person has died and a dozen injured when a plane crashed near Wonderboom Airport, north of Pretoria, on Tuesday.

"Our medical services are currently on the scene. They've been treating the patients," Russel Meiring, a spokesperson for emergency service provider ER24, told Xinhua by phone from Pretoria.

ER24 will move the treated patients to nearby hospitals, he said.

Details of the cause of the crash are yet to be established, but authorities confirmed that the plane hit a factory building before crashing.
