A South African court postponed the case against a state radio presenter accused of organising the recruitment of people to fight for Russia against Ukraine for further investigation.

Nonkululeko Mantula, an employee of the South African Broadcasting Corporation, and four men she is accused of helping travel to Russia to fight, appeared at the Kempton Park Magistrates Court near Johannesburg on Tuesday. The case was postponed to April 29.

The five have not yet been asked to plead and their bail conditions remain the same.

Mantula was arrested at Johannesburg’s main airport in November alongside her co-accused. Her arrest came amid mounting concern that South Africans and other Africans are being recruited by Russia for its war.

Earlier in the month, Duduzile Zuma-Sambudla, a daughter of former South African President Jacob Zuma, was linked to recruiting about 20 young men to go to Russia for a bodyguard-training course. When they got there, they were forced into the army, family members have said.

Kenya has said about 200 of its nationals were recruited to fight for Russia.

Working as a mercenary or fighting on behalf of another government, or assisting their military, has been a crime in South Africa since 1998.
