At least one person was killed when Ugandan police fired live bullets and tear gas to disperse crowds protesting the arrest of opposition leader Kizza Besigye.
The victim appeared to have been shot in the head and was lying in a pool of blood at a local market. Local media reported two more people had been killed.
Smoke billowed over the capital Kampala after crowds burned tires to block roads. Protesters stoned shops and cars to express their anger at Besigye being beaten, pepper-sprayed and dragged away by police yesterday, all shown on TV footage.
Mr Besigye, who has now been arrested four times this month during demonstrations against high food and fuel prices, was later released on bail.
Uganda's Interior Minister was scheduled to hold a news conference over the protests later today.
Loud explosions rocked the capital as military police fired live rounds at buildings where some protestors fled to evade arrest, leaving empty casings littered on the streets. Most shops in downtown Kampala were shuttered and the roads deserted.
Uganda's opposition has termed the government's decision to spend $720.6 million on Russian fighter jets as a misuse of meager resources.
Mr Museveni, in power since 1986, blames drought for high food costs and soaring oil prices for surging local fuel costs, and has warned Besigye that his protests will not be tolerated.
Mr Besigye lost a presidential election to veteran President Yoweri Museveni in February for a third time and has vowed to continue campaigning despite repeated detentions during the protests that had killed at least five people before today.
