Equatorial Guinea's President Teodoro Obiang Nguema has been re-elected with 93.7% of the vote in Sunday's election, according to official results.
Observers said polling day was peaceful and without incident, but the opposition claimed at least 200 of its members were barred from voting.
Mr Obiang, 73, has ruled the tiny oil-rich West African nation since 1979 after a military coup.
Rights groups describe him as one of the continent's most brutal dictators.
In 2009, he was re-elected with 95.37% of the vote.
The election commission put Sunday's turnout at 93%.
President Obiang is Africa's longest serving leader and has been pursued in French courts for allegedly plundering state coffers to buy luxury homes and cars in France.
His son and vice-president, Teodoro 'Teodorin' Nguema Obiang, has been resisting attempts by the US administration to seize his assets, denying charges that they were bought with embezzled state funds.
