WHO Director-General Tedros Adhanom Ghebreyesus, who made the appointment Wednesday, said in a statement that he had listened to those expressing concerns.

Tedros said he had “reflected” on his offer to 93-year-old Mugabe. “As a result I have decided to rescind the appointment.”

“I have listened carefully to all who have expressed their concerns, and heard the different issues that they have raised,” he said.

Mugabe, the world's oldest head of state, has long been criticized at home for going overseas for medical treatment as Zimbabwe's once-prosperous economy falls apart. Mugabe also faces U.S. sanctions over his government's human rights abuses.
