JOHANNESBURG -- In an extraordinary move, Ghana on Wednesday chartered a flight to repatriate about 300 of its citizens living in South Africa, Ghanaian officials said. The mass repatriation came amid rising anti-immigrant protests in South Africa, where for nearly two decades the authorities have been troubled by violent anti-migrant attacks, mostly on Africans. Several African leaders have forcefully condemned such attacks, while South African government officials deny allegations of xenophobia.
