Gabon coup: Ali Bongo appeal for help from his 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 had annulled the results of Saturday's election in which Mr Bongo was declared the winner, but the opposition claimed it was fraudulent.

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