A total of 397 Nigerians are currently undergoing screening to leave South Africa amid xenophobic tensions and anti-foreigner campaigns in the country.

The exercise, which began on Thursday and is expected to end on Sunday, is being supervised by the South African Police Service, the Department of Home Affairs, and the Department of International Relations and Cooperation.

This was disclosed by the President of the Nigerian Citizens Association in South Africa, Reverend Frank Onyekwelu, on Friday.

Onyekwelu said over 600 Nigerians had applied to return home for various reasons, but only 397 were cleared for the first evacuation flight after screening.
