The president of South Africa has warned that the country's coronavirus outbreak is going to get much worse, while announcing that lockdown measures are to be eased.

Cyril Ramaphosa said a third of the country's more than 22,000 cases had been recorded in the last week.

Despite that, the president said the current lockdown could not be sustained indefinitely.

He announced that, from 1 June, more restrictions would be lifted.

Mr Ramaphosa was speaking after a mining company in South Africa said 164 workers at a gold mine near Johannesburg had tested positive for coronavirus.

There have so far been 429 recorded Covid-19 deaths in the country.

How will the lockdown measures be eased?

An overnight curfew will no longer be in place, more businesses will be allowed to open and schools will re-start, the president said.

A controversial ban on alcohol will also end with limited sales allowed for home consumption only. A ban on the sale of cigarettes will remain.

The president has been under pressure to ease lockdown measures to restart the economy.

However, he warned the public that the worst is still ahead.

"We should expect that these numbers will rise even further and even faster," he said.

"The coronavirus pandemic in South Africa is going to get much worse before it gets better," he added.

What's happening at the Mponeng mine?

The Mponeng mine is the deepest gold mine in the world.

Operations have been halted after 164 cases of coronavirus were detected there. Most of those who tested positive were not showing any symptoms.

They have all been put into isolation, according to the mine's owners, AngloGold Ashanti.
