Kenya's president has launched a $14.5bn (£9.1bn) project to build a new city intended to be an IT business hub and dubbed 'Africa's Silicon Savannah'.

It will take 20 years to build Konza Technology City about 60km (37 miles) from the capital, Nairobi.

It is hoped that more than 20,000 IT jobs will be created in Konza by 2015, and more than 200,000 jobs by 2030.
