Nigeria has summoned South Africa's acting High Commissioner over a spate of recent attacks on foreigners in the southern African nation.
Nigeria will formally convey its "profound concern" at a meeting on Monday over incidents in South Africa, saying they could affect existing relations between the countries, according to a foreign ministry statement.
The meeting will focus on recent marches held by anti-immigrant groups and "documented instances of mistreatment of Nigerian citizens and attacks on their businesses", it said.
At least two Nigerians and four Ethiopians have been killed in recent weeks, local media reported, while there have been attacks on citizens of other African countries.
As Africa's most industrialised country, people from elsewhere in the continent have long travelled to South Africa to seek work.
