South Africa's Durban floods: At least 20 die as rain and mudslides cause havoc

At least 20 people in South Africa have been killed in floods caused by days of heavy rain, the authorities say.

It happened in the coastal province of KwaZulu-Natal, where many people are still missing and emergency services are searching for survivors.

Some in the city of Durban are standing on rooftops awaiting rescue, but local media report that only one helicopter is available to lift people away.

Key roads across the city are shut and mudslides have destroyed many homes.

It comes as scientists warn that climate change is fuelling heavier rainfall than usual in southern Africa.
