Kenya's president announced on Tuesday that the siege of Nairobi's Westgate shopping mall was over, but said losses from the attack by Islamist gunmen were "immense" and 67 people had died.
"We have ashamed and defeated our attackers, that part of our task is completed," President Uhuru Kenyatta said in a televised address to the nation.
Kenyatta said 61 civilians and six members of the security forces died in the siege that also claimed the lives of three Indians. He said five attackers had been killed and that there were 11 suspects in custody.
"Our losses are immense," he said.
"We have been badly hurt, but we have been brave, united and strong. Kenya has stared down evil and triumphed. We have defeated our enemies and showed the whole world what we can accomplish."
The president also called three days of national mourning.
A group of attackers marched into the four-storey Westgate Mall at midday Saturday, spraying shoppers with automatic weapons fire and tossing grenades.
Somalia's al-Qaeda-linked Shebab said it carried out the attack.
Kenyatta said that "forensic investigations are under way to establish the nationalities of all those involved."
