Africa's longest-serving leader is extending his rule further as election officials say the president of Equatorial Guinea has won another term.

Teodoro Obiang, 73, took power in Equatorial Guinea back in 1979 following a military coup.

While the constitution has been changed to impose term limits in this former Spanish colony, those rules do not retroactively apply to him.

On Thursday, the country's election officials announced on a state media website that Obiang had won 93.7 percent of the vote. While the percentage is high, Obiang previously took in 95 percent or more in past elections, which have been criticized by rights groups.

Critics accuse Obiang of overseeing a deeply corrupt government that represses and tortures opponents.
