Archbishop Emeritus Desmond Tutu has once again been admitted to hospital, the Desmond and Leah Tutu Foundation said on Wednesday.
Tutu, who turned 88 in October, has been admitted for a "stubborn infection", his wife Leah told the foundation.
The Nobel laureate has been hospitalised several times over the past few years for treatment of a similar condition.
Tutu last month celebrated the Springboks' Rugby World Cup victory in Cape Town.
This is a developing story.
