Over the weekend, the US Embassy issued a warning, and it’s the second such alert in South Africa in less than a year.
The US government has warned of possible attacks at up-market malls in Johannesburg and Cape Town.
The security alert has been issued following public calls by Islamic militants to carry out global terrorist attacks during the holy month of Ramadaan.
In the warning issued on Saturday, the US government says it's been tipped off about terrorism plots targeting Americans living in South Africa.
