Various civic organisations, led by March and its leader Jacinta Zuma-Ngobese, gathered at the Protea Hotel in Midrand to outline their action plan following the June 30 deadline imposed on illegal migrants to leave South Africa.

Jacinta Ngobese-Zuma, the leader of the March and March movement, reiterated the need for illegal immigrants to leave the country by June 30.

Speaking at a media briefing on Wednesday, Ngobese-Zuma said they had the support of many South Africans.

"South Africans said they wanted to see the country taking shape and for illegal immigrants to self-deport."

Tensions over immigration have escalated in parts of the Western Cape, KwaZulu-Natal, and Gauteng, with protests in some areas directed at undocumented migrants. Some foreign nationals have begun leaving the country amid the unrest.
