Samuel Yawe, a prominent businessman in Kampala has been killed in the riots.
Yawe, a hardware dealer and owner of Wesige Mukama Hardwares, was shot and killed during Thursday's riots.
This brings to six the number of people reportedly killed in the riots. One was a security guard with Saracen. Another one is a police officer, who was shot at near the Total petrol station in the suburb of Nsambya by rioting youth after they disarmed him.
Three civilians were killed by police in the city centre, one in the Bwaise area, and another in Nateete.
The clashes began when the Katikiro of Buganda, Uganda's largest ethnic group, was blocked from traveling to Kayunga to prepare for Kabaka Ronald Muwenda's visit to Bugerere on Saturday.
Military Police took to the streets of Kampala, firing live ammunition to disperse Buganda pro-monarchist protesters.
President Yoweri Museveni was Thursday evening expected to address a press conference about the tensions.
Meanwhile, the government is yet to come out with a conclusive position on the Kabaka's visit to Kayunga.
Speaking to journalists earlier on Thursday, the minister for information Kabakumba Matsiko said the government would have a position before Saturday.
She said that consultations were ongoing but called for calm.
