Tension has eased in Gabon's capital after days of deadly rioting triggered by an announcement that President Ali Bongo narrowly won re-election in a vote the opposition says was stolen.
More than 1000 people were arrested in the protests that began on Wednesday and the opposition, led by Jean Ping who claims he is now president, said five people also died.
Shops began to re-open on Saturday and some traffic returned to the streets as the government sought to restore stability with mass arrests and a heavy security presence.
Bongo came to power in 2009 on the death of his father, Omar, who ruled the Central African country for 42 years, relying on patronage fuelled by oil wealth to buy off dissent.
The disputed election sparked the protests but discontent has risen in an economy hit by lower global prices for its crude exports and falling production.
Many citizens also say the fruits of oil wealth have been shared too narrowly.
Ping appealed to the American people in an op-ed in the New York Times to send a clear signal to Bongo that they would not tolerate a stolen election.
He also repeated a call also taken up by the European Union for the electoral commission to release results bureau by bureau to make it easier to detect any potential discrepancies.
"The people of Gabon voted for their leader, they chose me. They chose a change from the dynastic regime that has ruled our country since 1967," Ping wrote.
He earlier called for international intervention but there were few signs by Saturday of the kind of decisive external action Ping seeks.
French Foreign Minister Jean-Marc Ayrault appealed to all sides in the dispute to use constitutional means and called on the authorities to restore all social media and internet connections after days of interruptions and cuts.
Ayrault also welcomed a decision by the African Union to get involved.
The African Union's Peace and Security Council expressed concern over the violence, saying the situation could affect regional stability.
In a statement, the Council "called on all Gabonese stakeholders to demonstrate utmost restraint and make use of all available legal and constitutional channels to resolve any differences pertaining to the results of the elections."
