Human rights lawyer advocate George Bizos said Nelson Mandela would have been ashamed by the violent attacks on foreigners in South Africa. His comments came as a Nigerian group - Socio-Economic Rights and Accountability Project - yesterday called for the International Criminal Court to investigate Zulu King Goodwill Zwelithini for "hate speech".Comments the king made last month, in which he said foreigners should go back home, were believed to have incited xenophobic attacks.MTN and Shoprite are among the South African businesses with major interests in Nigeria.Said Bizos: "We are dealing here with hatred for foreigners."I am pleased that the majority of people of SA, universities, human rights organisations and schools have stood up to put an end to this hatred of foreigners."Speaking yesterday in Pretoria at a University of South Africa debate, he said he would never have imagined that South Africans "could display such cruelty against their brothers and sisters".He said his own family came to South Africa from Greece as refugees. He said he knew how it felt to be a foreigner, away from family and friends and confronted by a language he could not speak."Fortunately we were welcomed with open arms," he said.The xenophobic attacks have claimed seven lives so far . The government has since deployed the SA National Defence Force to help the police restore order and stem the spread of the attacks.Former ANC treasurer Mathews Phosa has blamed lack of quality leadership for the crises that are enveloping the country, citing recent concerns about virtually every major parastatal from SABC and the SA Post Office to South African Airways and Eskom.He said: "Corruption is rife and that is what is wrong. We take bribes and kickbacks."Phosa said: "It makes me worry that people with the right skills are not appointed. There are more protests than during apartheid."Said Bizos: "When we remind ourselves of the words of the Constitutional Court and the dilemma it faced in not wanting to overburden the state financially when considering the realisation of rights, it sickens me to think of the billions of rands lost to corruption and maladministration."Bizos called for active citizenry and for the populace to "act in accordance with our ethical barometers to expose wrongdoing, seek accountability and play our part to help the lives of others in this country better".
