Pretoria, S. Africa - Former South African President Nelson Mandela remains gravely ill, though his condition improved slightly overnight.
The 94-year-old national icon is still in critical condition.
He is now in his 21st day in a Pretoria hospital fighting a recurring lung infection.
Hundreds of family members and friends continue to gather outside the hospital.
Mandela's oldest daughter said her father's long-term prognosis doesn’t look good.
