A Deadline for Migrants to Leave, Set on Facebook
By late July 2026, an anti-migrant campaign that began as an online movement has helped drive tens of thousands of foreign nationals from their homes across South Africa, aid agencies say. Doctors Without Borders launched an emergency response this month as vigilante groups — chief among them Operation Dudula, born on social media — set deadlines for migrants to leave, and in places enforced them with violence.
The ultimatum spread first as a date. Undocumented foreigners, the message ran, had until June 30 to leave South Africa. One of the men who claimed authorship of it, Nkosikhona Ndabandaba, told CNN he was the architect of the deadline. Ndabandaba, who uses the online name “Phakel’umthakathi” and has more than 1.7 million followers on Facebook, said migrants did not need to wait: “June 30 is the deadline, but you don’t have to wait until then – leave now.” After the date passed, he added, he could not control what other South Africans did.
For migrants, the message arrived as a threat. One foreign national told CNN he had been warned he would “leave in a coffin” if he stayed past the deadline. Others described being stopped in the street and ordered to produce identity documents, and being turned away from clinics and shops, according to reporting by NPR.
A movement that started on a feed
Operation Dudula — the name means roughly “push back” or “force out” in isiZulu — did not begin in the streets. It grew out of a social-media campaign called “Put South Africa First,” which circulated on Twitter during the coronavirus pandemic and blamed foreign nationals for unemployment and crime, according to Al Jazeera. That online movement, which first renewed and popularized anti-immigrant campaigns before finding expression on the ground, hardened into Operation Dudula in 2021. By 2026 its messaging, and that of a newer movement called March and March, was again setting the terms of a nationwide mobilization, Al Jazeera reported.
The pattern is one researchers and human-rights bodies have documented elsewhere: hostility toward an identifiable group, amplified online and rewarded with attention, migrates from the feed into physical action faster than any moderation can follow. In South Africa, the digital ultimatum did not stay digital.
From posts to the streets
As the deadline arrived, protests spread across the country. South African police arrested more than 900 people during the anti-migrant demonstrations, which were mostly peaceful but at times turned violent, with shops looted and one person shot dead, Al Jazeera reported. The violence has been fatal for some. Mozambique’s government said five of its citizens had been killed in xenophobic attacks in South Africa, according to Al Jazeera. Police in KwaZulu-Natal opened a murder investigation after a man was killed amid the rise in anti-migrant attacks.
Nigeria said it saw no sign the violence against its nationals was waning, and the attacks have strained South Africa’s relations with several African governments. The African Commission on Human and Peoples’ Rights deplored the attacks and vigilante conduct and urged authorities to protect foreign nationals.
Tens of thousands displaced
The flight has been large-scale. Thousands of Malawians, including hundreds of children, sheltered in an open field in the port city of Durban after fleeing threats and attacks, Al Jazeera reported. On July 9, Doctors Without Borders warned of growing humanitarian needs and disruption to health care after the displacement of “tens of thousands of people,” and said it had launched an emergency response for those cut off from medical care by the violence and intimidation, according to Al Jazeera. The medical charity said it was “deeply saddened to see people fleeing harassment and violence.”
Organizers have vowed to continue holding protests until their demands are met, and rights groups say the online campaigns that set the deadline are still running. South Africa has seen waves of xenophobic violence before; what the current wave shows, again, is how quickly a grievance packaged for a social feed can become an order that people in the street feel entitled to enforce.
