South African anti-apartheid icon Desmond Tutu has been admitted to hospital in Cape Town "for treatment of a stubborn infection", his office said on Wednesday.
The 88-year old retired archbishop has been receiving treatment for prostate cancer for more than 15 years.
He was last hospitalised in September 2018 for "a series of tests" and discharged after two weeks.
"Archbishop Emeritus Desmond Tutu has been admitted to hospital for treatment of a stubborn infection," said his wife Leah Tutu in a statement issued by the Desmond & Leah Tutu Legacy Foundation.
"The Archbishop has been hospitalised several times over the past few years for treatment of a similar condition."
