U.S. President Barack Obama, centre right, arrives for a news conference with South African President Jacob Zuma, centre left, at the Union Building on Saturday, June 29, 2013, in Pretoria, South Africa. The visit comes at a poignant time, with former South African president and anti-apartheid hero Nelson Mandela ailing in a Johannesburg hospital. The White House issued a statement Saturday that President Barack Obama plans to visit privately with relatives of former South African President Nelson Mandela, but doesn't intend to see the critically ill anti-apartheid activist he has called a "personal hero."
