Former Mali President Ibrahim Boubacar Keita is receiving treatment at a private medical clinic in the capital, Bamako.
Media reports say Keita was admitted to the Pasteur Clinic late Tuesday, 10 days after he was detained during a military coup by members of the National Committee for the Salvation of the People, who are now in power.
The condition of the 75-year-old former leader and the nature of his ailment have not been made public.
