Kenya's Interior minister has denied that the police used excessive force during Wednesday's protests in which at least 10 people were killed, describing them as "terrorism disguised as dissent" and an "unconstitutional attempt" to change the government.

A court in Kenya has given police 15 days to complete investigations of two police officers suspected of shooting and wounding a hawker during the latest street protests over the death of a blogger in custody.

Kenya's Interior Minister Kipchumba Murkomen accused protesters on Thursday of attempting to overthrow the government during a day of deadly demonstrations, remarks that protest leaders said were an attempt to deflect attention from their demands.
