Voting has started in Uganda's general election in which the country's long-time president faces seven opponents.

Because of delays in delivering voting materials, voting stated late at many polling stations, and at some stations voting had not even started several minutes after the official opening time.

President Yoweri Museveni faces a strong challenge from his main rival, Kizza Besigye, who says he does not believe the election will be free or fair.

Museveni has said he needs more time to implement his development programs. Ugandans are also choosing lawmakers.

There were long lines at many polling stations in the capital, Kampala, with people complaining loudly about the delays.

More than 15 million people are registered to vote. Polls close at 4 p.m. local time.
