Burkina Faso's ousted president, Roch Marc Christian Kabore, "is physically well" and is being held by the army in a villa, according to AFP, citing a source in his party on Wednesday.

"President Kabore is physically well, but I cannot say anything about his state of mind," said a source in Kabore's People's Movement for Progress (MPP) party.

Kabore "is still in the hands of the army, not in a military camp, but in a presidential villa under house arrest," the source added. "He has a doctor available... (and) access to his mobile phone, but under surveillance, obviously."
