Police in Uganda say two people have been shot dead and four others wounded at a gathering for opposition leader and presidential candidate Kizza Besigye.
Witnesses say a man opened fire after supporters of Besigye accused the man of being a government security agent and pelted his car with stones. Police are hunting for the shooter, who fled the scene.
Besigye was unhurt in the incident, which took place as he met with Buganda tribal leaders outside the capital Kampala Wednesday.
The shooting occurred hours after a Ugandan judge adjourned Besigye's trial on treason charges until after the February 23 presidential election.
Besigye has denied charges of rape and treason that supporters say were lodged to derail his campaign.
Besigye is challenging President Yoweri Museveni, who is seeking to extend a 20-year rule critics say has becoming increasingly autocratic.
