Uganda's electoral commission says President Yoweri Museveni has won a new five-year term, but the president's main rival is rejecting the election results.
The commission announced Sunday that Mr. Museveni won Friday's presidential election with 68 percent of the vote. His closest challenger, Kizza Besigye, was a distant second with 26 percent.
In a statement Sunday, Mr. Besigye and his four-party coalition said they categorically reject the outcome of the elections. They also said any government formed by Mr. Museveni would be illegitimate.
Mr. Besigye told reporters said he has not ruled out calling for street protests, although he has not yet done so. The opposition leader has previously said Uganda is ready for an Egypt-style uprising.
President Museveni has ruled Uganda since seizing power in 1986.
Before Friday's election, Mr. Besigye accused the government of trying to rig the vote. President Museveni denied the charge.
Mr. Besigye is Mr. Museveni's former physician and has challenged him three times for the presidency.
About 14 million Ugandans were registered to vote in the presidential and parliamentary elections. These were the fourth elections in Uganda since the return of multiparty polls in 1996.
