The death toll from floods in South Africa's KwaZulu-Natal province (KZN) has climbed to 443, the premier of the province said at a news briefing on Sunday, adding that 63 more people were still unaccounted for. 

More than 13,500 households have been seriously affected by the floods, South African news outlet HeraldLIVE reported, citing human settlements minister Mmamoloko Kubayi.

The floods caused at least 10 billion rands ($684.58 million) damage in KZN, a senior provincial official said on Sunday, as rescuers searched for the missing, and more rain was expected.
