Hundreds of people have marched in Uganda to protest a bill that would allow President Yoweri Museveni to seek a third term in office.

Opposition groups organized Thursday's march in Kampala, which included handing a statement to Britain's embassy.

In the statement, critics accuse Uganda's government of seeking a constitutional amendment to end a two-term limit in order to establish a "dictatorial presidential monarchy."

Mr. Museveni has not publicly declared if he will stand in elections next year.

Monday, government supporters held a rally to dismiss foreign criticism of a proposed third term for the president.

Mr. Museveni has agreed to allow multi-party elections next year for the first since he took power nearly 20 years ago.
