Of the dead was a GSU police officer who succumbed to injuries while undergoing treatment.
Inspector General of Police, Joseph Boinnet, said 28 other people were admitted at various hospitals where they were receiving treatment.
Of the dead, the IG said, 16 were Kenyans, an American, Briton and three other victims of African decent who were yet to be identified.
Already, police have arrested two people whom they believe facilitated the Tuesday afternoon attack at the complex housing the dusitD2 hotel and several other office buildings.
One suspect was arrested in Ruaka inside a house where a terrorist was living since November last year while another one was arrested in Eastleigh Estate.
Five attackers, who were all killed by Special Forces, had frequented the complex weeks before they executed the attack.
Meanwhile, the hunt on more suspects who collaborated with the five terrorists behind the Dusit Complex terror attack is ongoing. Police say they have increased security at the main border points to deter any of the collaborators from fleeing the country.
Detectives handling the issue say they believe there are more collaborators still out there and that they are pursuing crucial leads into their whereabouts.
