JOHANNESBURG -- Beyonce and other international stars have gathered in South Africa for a charity concert honouring Nelson Mandela, a century after he was born.
Pharrell Williams, Trevor Noah and Oprah Winfrey were among those headlining the Global Citizen Festival: Mandela 100 at Johannesburg's FNB Stadium on Sunday. Model Naomi Campbell and singer Bob Geldof, who organized the Live Aid concerts for Africa, are also attending.
Global Citizen, an advocacy group, campaigns for an end to extreme poverty and other causes. It says many people won tickets to Sunday's concert through charity work and petition-signing.
South African media say a concert worker died in a stadium fall Saturday.
World leaders gathered at the stadium for a 2013 memorial after the death of Mandela, the anti-apartheid leader and South Africa's first black president.
