Gabonese security forces stormed the headquarters of the defeated presidential candidate, Jean Ping, as unrest continues after Saturday’s disputed election.
A government spokesman said the operation in the capital, Libreville, was aimed at rooting out criminals.
The election result, announced on Wednesday afternoon, gave Mr Bongo a second seven-year term with 49.8% of the vote to Mr Ping’s 48.2 %, a margin of 5,594 votes.
Mr Ping said the election was fraudulent and “everybody knows” he won.
Mr Bongo took office in 2009 after an election marred by violence, succeeding his father Omar Bongo who had come to power in 1967.
Mr Ping had been a close ally of Omar Bongo, serving him in ministerial roles and having two children with his daughter, Pascaline, a former Gabonese foreign minister herself.
