Along the beach, campaign portraits still line the road. It's just another sign of an ongoing post-election battle.

Ali Bongo has been officially confirmed as the winner of the presidential election. But two others candidates still claim victory: former home affairs minister Andre Mba Obame, and Pierre Mamboundou, a long-time leader of the opposition.

Andre Mba Obame, who keeps his security guards with him at all times, explains: "My life is in danger because the president announced that I cannot work as long as I am alive - I can't establish myself in the country. He (Ali Bongo) was proclaimed president, but it's me, everyone knows it - it's me, you know, that won the presidential election the numbers show that... "

Ali Bongo was officially declared the winner with 42 percent of the vote. Mba Obame garnered 26 percent, followed by opposition leader Pierre Mamboundou with 25 percent.

Bongo's victory sparked a three-day riot earlier this month in the harbour city of Port-Gentil, an opposition stronghold. Amateur video footage showed the police struggling to contain an angry mob.

The government says that three people died during the violence, but the opposition says the number is closer to at least 15 and has asked for an international investigation into those deaths.

Gabon's defeated presidential candidate Andre Mba Obame said he had taken legal action to annul the results of last month's disputed poll.

Other candidates have until Sept 19 to take action. Final results will be given within a month. Until then, the situation on the ground remains unstable.
