South African President Cyril Ramaphosa on Monday condemned recent anti-immigrant violence in the country, saying “opportunists” were exploiting social grievances to fuel attacks against foreign nationals.

In an open letter released by his office, Ramaphosa said xenophobia and violence had no place in South Africa and stressed that recent protests targeting migrants did not reflect government policy or the views of most South Africans.

"The recent violent protests and criminal acts directed at foreign nationals in parts of our country do not represent the views of South Africa's people," he said.

The South African leader said some individuals were using community frustrations as a cover for unlawful actions, including stopping people to demand identification documents and conducting illegal property searches.

His remarks come amid growing diplomatic concern across Africa following renewed anti-migrant demonstrations and reported attacks on foreign nationals in several South African cities.

Nigeria last week announced plans to repatriate at least 130 citizens from South Africa, following fears of escalating xenophobic violence. Nigerian authorities also called for investigations into the deaths of two Nigerians in separate incidents involving South African security personnel.

Ghana has also raised concerns and summoned South Africa's ambassador over reported acts of xenophobia.

Ramaphosa acknowledged that undocumented migration places pressure on public services, including healthcare, housing and municipal infrastructure, particularly in poorer communities.

He said the government would continue addressing illegal immigration "within the law," while strengthening border security and enforcing labor regulations against employers hiring undocumented workers.

The president said South Africa's Border Management Authority had intercepted around 450,000 people attempting to enter the country illegally during the past financial year.

He also announced increased workplace inspections and renewed efforts to combat corruption within the immigration system.

South Africa has experienced recurring outbreaks of anti-immigrant violence over the past two decades, with migrants from other African countries frequently targeted during periods of economic hardship and high unemployment.
