The wife of Gabon’s ousted president Ali Bongo Ondimba has been charged with “money laundering” and other offences, the public prosecutor said Friday, a month after a coup toppled her husband.

Sylvia Bongo Ondimba Valentin, who is Franco-Gabonese, and one of the couple’s sons have been accused by the coup leader of having pulled the strings in the oil-rich country.

Their eldest son, Noureddin Bongo Valentin, has already been charged with corruption and embezzling public funds with several former cabinet members and two ex-ministers.

Sylvia Bongo was charged by an investigating judge on Thursday and ordered to remain under house arrest, Andre Patrick Roponat announced on state TV channels.
