Malawian activists have demanded that action be taken against King Zwelithini and Jacob Zuma's son for making remarks that were viewed as inciting xenophobic violence.
The activists in Lilongwe said unless action was taken against the two within 48 hours, they would force South African businesses in their country to close down. About 200 marchers presented a petition to South African High Commissioner Cassandra Mbuyane-Mokone yesterday.
Malawian police have also been out in force on the streets of the capital in case of reprisal attacks against South African businesses.
News24 reported that South Africa had closed its embassy in Lagos, Nigeria, after anti-xenophobia protests there.
In Botswana, routine patient referrals to South Africa have reportedly been suspended.
