Ugandan opposition leader Kizza Besigye is in intensive care in hospital, his wife and medical sources said on Thursday, as the UN blasted a wider crackdown on dissent. His wife Winnie Byanyima, the executive director of UNAIDS, wrote on X: "He has been admitted to the ICU at Mulago Hospital (in Kampala). A spokeswoman for the hospital, Gladys Baligonzaki Kajura, confirmed to AFP that Besigye had been admitted. Besigye, a former personal physician to Museveni, has been in the government's crosshairs since he joined the opposition more than 25 years ago. Uganda has imposed a widening crackdown on opposition figures, lawyers and independent media in recent months.
