Large crowds have gathered in Johannesburg as anti-migrant groups intensify protests ahead of a self-imposed June 30 deadline demanding that undocumented migrants leave South Africa.

The demonstrations have heightened tensions across the country, with authorities on high alert over fears the protests could escalate into violence. Security has been reinforced in several areas as law enforcement agencies monitor the situation closely.

The protesters argue that undocumented migration has contributed to rising unemployment, crime and increased pressure on public services. However, migration experts and independent researchers have challenged these claims, maintaining that there is limited evidence linking undocumented migrants to the country's broader economic and social challenges.

The June 30 deadline, widely circulated on social media by anti-migrant groups, is not an official directive of the South African government. Authorities have dismissed reports suggesting otherwise and warned the public against misinformation capable of inciting fear and unrest.

President Cyril Ramaphosa has condemned xenophobia and urged South Africans to remain calm, stressing that no individual or group has the authority to forcibly remove people from the country or take the law into their own hands. He reaffirmed the government's commitment to protecting everyone living in South Africa, regardless of nationality, while ensuring immigration laws are enforced through legal processes.

The rising tensions have prompted growing concern among migrant communities, with thousands of foreign nationals reportedly seeking assistance from their embassies or making plans to leave the country amid fears of possible attacks. Several neighbouring countries have also begun facilitating the voluntary return of their citizens.

The latest protests have revived memories of previous outbreaks of xenophobic violence in South Africa, where attacks targeting foreign nationals resulted in deaths, injuries and the destruction of homes and businesses.

As the June 30 deadline approaches, authorities have urged residents to remain peaceful, avoid taking the law into their own hands, and report any acts of violence, intimidation or criminal activity to security agencies. Investigations and security operations remain ongoing as officials work to prevent any breakdown of law and order.
