Thousands of anti-immigration protesters took to the streets across South Africa on Tuesday as demonstrations demanding the removal of undocumented foreigners began under heavy police presence, raising fresh concerns among foreign nationals, including Nigerians.

Videos shared online showed large crowds marching through Johannesburg, where protesters demanded that undocumented immigrants leave the country.

The protest followed an unofficial June 30 deadline earlier issued by anti-migration campaigners for undocumented foreigners to leave South Africa.
