Major disruptions are being reported at Durban and Richards Bay amid unrest following the jailing of former South African President Jacob Zuma.

The South African Association of Freight Forwarders said the lack of health services at Durban, the country's principal port, had been effectively preventing vessels from berting due to lack of Covid-19 testing, Reuters reported.

Meanwhile, state-owned logistics outfit Transnet told the newswire that "the entire supply chain is closed" there and at Richards Bay, including roads into and out of the ports.
