Nigeria Urges Against Retaliation to South African Xenophobia Darren Taylor JOHANNESBERG, SOUTH AFRICA - With anti-immigrant violence sweeping parts of South Africa, Nigeria on Wednesday urged its citizens to refrain from vengeance -- even as at least two major South African-owned companies have suspended some operations there because of attacks.
