South African Police Arrest 90 As President Ramaphosa Condemns Xenophobic AttacksSouth Africa's president condemned days of widespread looting and arson attacks on foreign-owned businesses across Johannesburg and the capital Pretoria, calling the violence "totally unacceptable." "We are a country that is completely committed against xenophobia," President Cyril Ramaphosa said in a video statement published Tuesday on Twitter. "We do not allow and cannot tolerate attacks on people from other African countries." Police fanned out across neighborhoods in Johannesburg and Pretoria as the violence extended into a third day in South Africa. \n\nPolice have arrested more than 90 people in five areas impacted by the violence. Many gutted, emptied shops remained closed as shop owners, many of them foreign, feared to return to their property. "There is no justification whatsoever for people who have a sense that their jobs are being taken by people from foreign lands to attack them, to destroy properties, and actually to kill them," said Ramaphosa. "This must be stopped." WARNINGS TO FOREIGNERS\n\nOn Monday, African governments warned citizens living in South Africa to take safety precautions and expressed frustration with the latest wave of attacks targeting foreign-owned businesses in South Africa. The Ethiopian Embassy in South Africa advised citizens to close their shops "until peace is restored," according to Ethiopian media, and Zambia's Ministry of Transport and Communications warned Zambian truck drivers not to travel in to the country. Nigerian President Muhammadu Buhari said he has dispatched a Special Envoy to South Africa to convey his concerns to Ramaphosa. \n\nBuhari's office said he has also instructed the Minister of Foreign Affairs, Geoffrey Onyeama, to summon the South African High Commissioner to Nigeria and get a brief on the situation, express Nigeria's displeasure over the treatment of its citizens, and to get assurances of the safety of their lives and property. Onyeama called the violence "sickening" Monday on Twitter.
