The Democratic Alliance (DA) has on Monday laid criminal charges against EEF leader Julius Malema and party member Nazir Paulsen for "inflammatory" social media posts.
DA Chief Whip, Natasha Mazzone said the tweets incite violent.
The accusation follows Malema's tweet, which read in part: "magwala a chechele morago, loosely translated coward move to the back, fighters attack!" fighters attack!" and a photo of a machine gun.
Paulsen's post includes a photo of himself entitled "Get Ready!" following Malema's initial tweet.
“The DA strongly condemns this reckless attempt by the EFF leadership to further violence at this increasingly delicate time in South Africa’s democratic dispensation.
We have seen some posts from EFF over the weekend showing pictures of supporters with guns and gunfire published on video in support of Malema's tweet, "said Mazzone.
Mazzone said EEF is showing its true colours, adding that Malema and his thugs have nothing to do with the rule of law. Their only contribution to the political landscape in South Africa is chaos, violence, and a clear attempt to destroy democratic institutions.
She said DA had referred Malema and Paulsen to the parliament's ethics committee to request an investigation into this inflammatory allegation, which constituted a grave breach of their oath.
"The South African Police Services (SAPS) can no longer stand idly by and ignore Malema's violence, especially given the speed with which police action and energy are in pursuing the alleged triggers of violence in Senekal," said Mazzone.
Mazzone said the ball was in Parliament and before police and courts to force Malema and his quasi-revolutionary group to account for their brazen incitement of violence.
