Scores of world leaders planning to attend Mandela memorial

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. As a result, the government announced Sunday three overflow venues where the event will be broadcast live -- at Ellis Park Stadium, Orlando Stadium and Dobsonville Stadium. Additionally, some 90 screens will be set up across the country to show all planned national events.

Security for the Tuesday event is likely to be tight as the list of presidents, heads of government, royalty and celebrities keeps growing by the hour. Defense Minister Nosivewe Mapisa-Nqakula, who is overseeing security, said 11,000 troops have been deployed. She said a coordinated plan involving the military, the air force and police across the country is in place to control and protect tens-of-thousands of mourners.

Below is a selection of confirmed attendees.

- U.S. President Barack Obama and first lady Michelle Obama as well as former presidents George W. Bush, Bill Clinton and Jimmy Carter. Twenty-six Congressmen will also attend.
