Kenyan authorities say they are still holding eight people in connection with the deadly four-day siege at a Nairobi shopping mall.
Interior Minister Joseph Ole Lenku told reporters Friday that authorities have released three other suspects.
Earlier this week, officials said five suspected militants were killed as troops and police worked to regain control of the Westgate mall.
The official total death toll from the siege stands at 72.
Investigators continue to sift through the wreckage at the partially collapsed mall. On Friday, the Kenyan Red Cross said 59 people remain missing following the attack.
Lenku said no additional bodies have been recovered from the site.
The Somalia-based al-Shabab extremist group claimed responsibility for the attack and is vowing to carry out other acts of violence against Kenya.
On Twitter Friday, the militant group said its attack on the Westgate mall was "just the premiere of Act 1."
