KAMPALA (Reuters) - Fuel and basic commodity shortages in landlocked countries neighbouring Kenya, which is wracked by political unrest, have eased but traders are hoarding supplies and prices have risen steeply.

Kenya is the gateway to several other eastern African nations such as Burundi, Rwanda, Uganda and Southern Sudan.

Political unrest in Kenya after the disputed re-election of President Mwai Kibaki has killed more than 600 people and has resulted in transport problems that have choked supplies.

Police have had to escort convoys of fuel tankers through dangerous sections of the Mombasa-Kisumu highway that is the main supply artery into the neighbouring countries.

Uganda continued to suffer scarcity of fuel although tankers were now arriving in Kampala.

"We have instituted a technical team to investigate why we import sufficient petroleum products but the fuel pumps (operators) claim that they are dry," Energy Minister Daudi Migereko told Reuters.

"We strongly suspect that businessmen are simply hoarding the fuel to make more profits, which is illegal."

Uganda has said it would diversify supply routes to Tanzania and lay a pipeline linking Kenya to its capital, Kampala. The country is a key link to north-eastern Democratic Republic of Congo, Rwanda and southern Sudan.
