You can buy coke and chips, but no cigarettes or alcohol: what we know about South Africa's lockdown
South Africa enters a national shutdown on Friday, 27 March. From one minute after midnight, South Africans will be expected to stay home except under very specific circumstances, and businesses that are not essential must be shut down.
Failure to comply with the rules could lead to a month in jail, or a fine.
Police minister Bheki Cele has announced that no alcohol will be sold during the lockdown and that people may not transport alcohol from one point to another. Cele also reiterated that no restaurants will be allowed to operate during the 21-day lockdown. Go buy your food and cook it at home, he said.
Perpetrators found guilty of lockdown offences will get a fine or six months in jail, or both.
