Kenyan and foreign forensics teams are searching the Westgate shopping complex in Nairobi amid uncertainty over how many bodies they may find following the four-day siege by Islamist militants.
Sixty-seven people are so far known to have died.
Kenya's interior minister has said he does not expect the toll to rise significantly, and believes only the bodies of militants will be found.
But Kenya's Red Cross has said 61 people remain unaccounted for.
Meanwhile Kenya is continuing three days of official mourning for both the civilian and military victims of the siege.
