JOHANNESBURG — Nelson Mandela remains in a South African hospital, where he is in critical but stable condition.

There was no official update Monday morning on the health of the 94-year-old former president and anti-apartheid leader, who was admitted June 8 to the hospital for a recurring lung infection.

People in South Africa and around the world have expressed concern for Mandela, sending messages of support for a man seen as a global symbol of reconciliation.

Mandela spent 27 years in prison during white rule and was released in 1990. He led the shift from apartheid to democracy and became president in all-race elections in 1994.
