President Cyril Ramaphosa has sent a message of condolence to his Zambian counterpart Edgar Lungu, following the death of 11 Zambian nationals in a bus accident that took place on Monday, outside Mookgopong, in Limpopo province.
Ramaphosa also wished all the injured victims a speedy recovery.
Local law enforcement agencies are investigating the cause of the accident.
Working with Zambian authorities through their High Commission in Pretoria, the South African government will provide assistance to the injured and the families of all the deceased, the Presidency said.
Relations between South Africa and Zambia were cemented when the ANC established its headquarters in Lusaka during the struggle for liberation.
