JOHANNESBURG — The doctors treating former South African leader Nelson Mandela believe he should remain in Johannesburg for now to be close to medical facilities that can provide care to the 94-year-old, the government said Thursday. Mandela left a hospital Wednesday evening after nearly three weeks of treatment there, and was brought to his home in the Johannesburg neighborhood of Houghton. The anti-apartheid icon, also known by his clan name Madiba, has lived over the past year and more in the rural village of Qunu in Eastern Cape province. — AP
