Kampala - Three vehicles collided near Kampala late Friday night killing at least 20 people, many of them children, according to radio reports and witnesses.

The accident took place in Buryantente village, 45 kilometers east of the capital Kampala, when a school bus, a cement-carrying trailer and a small truck crashed into each other, Central Broadcasting Service radio reported.

A witness in the village told Deutsche Presse-Agentur dpa by telephone that the accident first involved a bus full of school children and a pick-up truck. Shortly afterwards, a cement-laden trailer crashed into the two vehicles.

Every year, motor accidents claim hundreds of lives on Ugandan highways and are often the result of speeding, the poor mechanical condition of vehicles and overloading. (dpa)
