Nigeria's high commission in South Africa has urged its citizens there to be cautious following an anti-illegal immigration protest in Eastern Cape province that turned violent.
On Monday, activists were holding a peaceful march in the port city of KuGompo (formerly East London). But disorder erupted after a protester said he was attacked by a foreigner, prompting demonstrators to damage several vehicles and shops.
The trouble came amid tension over the recent installation of a Nigerian community leader in the city, who has a traditional title that can be translated as "king of the Igbo people in East London".
Some South Africans in the local area saw this as an attempt to grab political power.
Xenophobic sentiment in South Africa has in recent years led to rounds of deadly violence.
