The Rustenburg farmer who brought a complaint of genocide with the International Criminal Court (ICC) against African National Congress Youth league (ANCYL) president Julius Malema and 11 others has set up a website to monitor farm attacks.

He has asked anyone with information about farm attacks to send him the details so he can convey the information to the ICC prosecutor in the matter every week.

"The weekly sending of farm attack statistics to the prosecutor was born as a result of the poor, outdated and totally unreliable statistics in this regard made available by the organs of our current government," his lawyer Fanie van der Walt said in a statement on Tuesday.

The website www.stopafrikanergenocide.co.za would also be used to keep people informed about the court case, said Van der Walt.

The unidentified Rustenburg farmer and his family reportedly left South Africa, fearing for their safety, after deciding to lay the charge against Malema.

He interpreted Malema's singing of the lyrics "shoot the boer", as incitement of ANCYL supporters to commit genocide against Afrikaans farmers.

Shortly after being rebuked by the ANC, Malema changed the words to "kiss the boer".

On Tuesday, Van der Walt said that the farmer had instructed him to address the prosecutor and assist him in his preliminary investigation.

He said that the Rome Statute stipulated that the prosecutor analyse the seriousness of the information received.

This could include seeking additional information "from States, organs of the United Nations, intergovernmental or nongovernmental organisations, or other reliable sources that he or she deems appropriate," and receiving written or oral testimony.

At the time the complaint was submitted on June 17, Van der Walt said that this would not automatically trigger an investigation.

All the information submitted had to be analysed before it was decided to prosecute.

"We believe however that the ICC will decide to formally investigate the complaints because they comply with the very specific and defined jurisdiction and mandate of the [court] as defined by the Rome Statute," he said.
