The search for schoolchildren swept away by floods in South Africa’s Eastern Cape province has resumed after being halted overnight, officials have said.

The children were on their way to school in the town of Mthatha when their bus was carried away in flood waters as it was crossing a bridge on Tuesday morning.

A total of eight bodies, including that of the bus driver, have so far been recovered, Eastern Cape community safety official Xolile Nqatha has told private TV station Newzroom Afrika.

Other officials said three students were rescued on Tuesday, but it was unclear how many pupils were on the bus, which has since been found on a riverbank with no-one inside.

Public broadcaster SABC reported that the three children who were rescued were found clinging to trees.

On Wednesday morning, Eastern Cape Premier Oscar Mabuyane visited the scene to witness rescue efforts, and to meet affected communities.

He told Newzroom Afrika that while the situation was a “difficult one”, he was “quite happy” with the response of the emergency services.

South Africa has been hit by heavy snow, rains and gale force winds that have officially claimed the lives of 14 people, nine from the floods and five in a road accident.

Nearly 500,000 homes were left without electricity on Tuesday – and state-owned power provider Eskom says efforts are being made to restore connections.

South Africa’s President Cyril Ramaphosa has offered his condolences to the families of those who died as he urged citizens to “display caution, care and cooperation as the worst impacts of winter weather take effect across the country”.

The Eastern Cape – the birthplace of anti-apartheid icon Nelson Mandela – has been worst-affected by the icy conditions, along with KwaZulu-Natal province.

The bad weather has forced the closure of some major roads in the two provinces to avoid further casualties.
