Cape Town - At least two Golden Arrow buses were torched before sunrise on Monday morning, as hundreds of commuters battled to get to work.
Taxi services were not operational after some associations went on strike on Monday morning.
The City of Cape Town's fire and rescue services attended to at least two fires, where buses were set alight.
Dramatic pictures and video footage sent to IOL shows buses ablaze as fire and rescue service personnel try to extinguish them.
"Dispatched 04:54 bus alight, protest-related, Shushu crescent, Khayelitsha," the City of Cape Town's Theo Layne said. "Two fire engines, one water tanker and one rescue vehicle with 14 firefighters were dispatched. No injuries have been reported."
Officers stationed at Harare, Khayelitsha, reported the fire at Makhaza.
Video footage sent in by Mariya Nel shows firefighters battling the blaze.
It was unclear whether or not the protest action believed to be responsible for the buses being torched was related to the taxi strike.
