JOHANNESBURG -- The memorial service for former South African President Nelson Mandela on Tuesday is poised to be one of the largest such gatherings in generations with tens of thousands of local mourners and dozens of foreign leaders expected.
South African officials say the normal seating capacity of Johannesburg's FNB stadium probably won't suffice to accommodate all mourners. Security for the event is likely to be tight as the list of presidents, heads of government, royalty and celebrities keeps growing by the hour.
The South African government said Sunday a total of 53 heads of state, government and ministers have confirmed they will be attending the service.
