NAIROBI - Kenya was hit by a nationwide power blackout on Saturday evening caused by a "system disturbance", electricity distributor Kenya Power said.

"We are working to restore normalcy within the shortest time possible," Kenya Power said in a statement.

Kenya Power is the country's sole electricity distributor and the bulk of its power comes from Kenya Electricity Generating Company (KenGen), which is the main producer.
