Kenya's energy regulator had to raise its retail price of petrol and diesel due to a weaker local currency and rising global oil prices.
The retail price of all grades of petrol will increase by 41 cents per litre, says the department of energy.
Refiners in South Africa are seeking nearly 80 000 tonnes of diesel for delivery in January through spot tenders issued late last week.
A little too late to benefit most motorists returning from their end-of-year holidays, the price of petrol and diesel is to drop next week.
The retail price of all grades of petrol will rise by 45 cents a litre on Wednesday next week, the Department of Minerals and Energy said on Friday.
