' DON'T PANIC'
Earlier today, State Security Minister David Mahlobo said government noted the terror alert by the US Embassy and assured the country that there was no need to panic.
On Saturday, the United States Diplomatic Mission published a statement on its website, warning Americans in South Africa about possible attacks.
Last month, a new message purporting to come from the spokesman of Islamic State, called on followers to launch attacks on the West during the Islamic holy month of Ramadan.
Some malls in Johannesburg and Cape Town have said they are now increasing their security.
In a statement released this morning, Mahlobo said security services of the country have liaised with the Americans on the concerns raised this weekend, and these engagements would continue.
Mahlobo said South Africa remained a strong and stable democratic country and there was no immediate danger posed by the alert.
The minister said security services would continue to work on matters of violent extremism and terrorism, to ensure the safety of all citizens and residents.
The State Security Department's Brian Dube said while they have taken the threat seriously, they also need to investigate the threat level.
"It is important that we look into the matter with our own analysis as we receive information from time to time, so when the information comes it is analysed, and we can determine the extent of the threat and how to respond to it."
