A transit accident in South Africa killed 45 people after a bus hit and plunged over the barrier of a bridge into a ravine, where it caught on fire, the nation’s transport department said Thursday. The only survivor was an 8-year-old girl, authorities said.

Footage of the scene broadcast by local news channel eNCA shows a charred, mangled bus at the bottom of a rocky ditch in a mountainous area near Mokopane, South Africa. Journalist Heidi Giokos from the outlet posted aerial footage showing the suspended section of the R518 road. The bus fell about 50 meters after going over the barrier.

The cause of the crash is under investigation, said South Africa’s Transport Minister, Sindisiwe Chikunga.

“Some bodies were burned beyond recognition,” the Department of Transport and Community Safety of Limpopo said in a statement. Others were trapped by debris, while some were scattered around the rocky crash scene, the department added. The 8-year-old survivor was brought to a hospital.

Another woman died after she was airlifted from the crash scene, Chikunga told eNCA.
