A car with a woman inside was swept off a bridge in Postmasburg, Northern Cape paramedics said today.
Emergency units, including the air wing, were searching for the woman, said ER24 spokesman Derrick Banks.
Earlier, there was an unconfirmed report of two children also being swept away in a car in the same vicinity.
The bridge, which leads to Kimberley, was closed off by authorities as a heavy downpour resulted in flooding.
People living in Postmasburg were also evacuated.
