Gabon coup: Army seizes power from Ali Bongo and puts him in house arrest

Gabon's President Ali Bongo has appealed for help after the army deposed him in a coup and put him under house arrest.

Speaking from what he said was his residence, he urged supporters to "raise your voice".

Earlier, army officers appeared on TV to say they had taken power.

They said they were annulling the results of Saturday's election in which Mr Bongo was declared the winner but the opposition said was fraudulent.

The officers also said they had arrested one of Mr Bongo's sons for treason.

Mr Bongo's overthrow would end his family's 55-year hold on power in Gabon.
