Black First Land First (BLF) president Andile Mngxitama — already in hot water for his rant about "killing white people" at the weekend — has upped the ante by launching a verbal attack on EFF leader Julius Malema.

Mngxitama called a media conference on Tuesday to clarify his comments made during the party's rally in Potchefstroom, North West, on Saturday.

Mngxitama came under fire after he had urged his supporters to kill five white people for every one black person killed.

"You kill one of us, we will kill five of you. We will kill their children, we will kill their women, we will kill anything that we find on our way," Mngxitama said.

The comments have been labelled by many as hate speech.
