Power has been restored to several parts of Kenya after a widespread blackout left large areas without electricity overnight. Kenya Power says supply has returned across the Mt. Kenya region, North Rift, Western Kenya, South Nyanza and parts of the capital, Nairobi. The outage, which began Wednesday evening, also affected parts of the Central Rift Valley, disrupting businesses and daily life. Kenya Power, which serves more than 9.6 million customers, has not yet explained what caused the latest outage.
