Burkina Faso's interim president Michel Kafando, who was deposed last week during a coup staged by presidential guards, will be returned to office on Wednesday, putsch leader General Gilbert Diendere told AFP on Tuesday.

The return of "Kafando is already a done deal. The (African) heads of state arrive tomorrow to put him back in office," Diendere said.

"Theoretically, it is me who will welcome them (at the airport) tomorrow and Kafando will go with them after that."
