The airline said in a notice that it was suspending until further notice flights to Johannesburg, Cape Town, Lusaka and Harare starting on Monday.
“In view of the global concerns on COVID variants prevalent throughout Southern Africa, RwandAir announces the suspension of its flights to Johannesburg, Cape Town, Lusaka and Harare, effective 8 February 2021,” the airline said.
Scheduled flights would resume “as soon as there is more clarity on the situation”, it said.
RwandAir had resumed Kigali-Lusaka-Harare-Cape Town flights in December after eight months of suspension following the COVID-19 lockdown in April 2020.
Rwanda joins several other countries that have suspended air travel to and from South Africa and Zimbabwe following the discovery of a new variant of COVID-19 in South Africa in December, which has been driving a second wave of infections in the country and neighbouring states.
The United Kingdom and United States have imposed travel bans on South Africa and other southern African countries.
