Sudan has removed all subsidies for imported fuel, doubling the price of petrol and diesel.
The price of petrol will rise from 150 Sudanese pounds ($0.35; £0.25) per litre to 290 pounds while diesel will now cost 285 pounds a litre from 125 pounds, according to the finance ministry.
It said subsidies cost the country a billion dollars a year.
The ministry added that despite the latest increase, the price of fuel in Sudan remained among the lowest in Africa.
Previous price rises have sparked protests.
Economic reforms carried out since the overthrow of the long-standing president, Omar al-Bashir, two years ago have contributed to the devaluation of the Sudanese currency and a huge rise in inflation to more than 300% a year.
