A military standoff with terrorists at a Kenyan mall was apparently drawing to a close Tuesday after four days of carnage left at least 61 civilians and six security officers dead.
Five terrorists were killed, and 11 other suspects are in custody, Kenya's president said. About 175 people were injured, he said.
As authorities indicated the siege was all but over, many questions will have to be answered, such as did the terrorists include Americans, a British subject and a Canadian national, as claimed by Al-Shabaab, the Islamic extremists who took responsibility for the gun attack.
For now, Kenya reels from a horrific terror attack at Nairobi's upscale Westgate Mall -- frequented by well-to-do Kenyans and the expatriate community -- which began just after high noon Saturday.
Day One: Saturday
It was a nice day at the 80-store mall. A cooking competition was held for youths, perhaps some aspiring to become chefs. Visitors stocked up on staples at a supermarket or sipped coffee at a cafe.
Without warning, gunmen stormed the mall, shooting people outside the five-story structure and then inside it. Shoppers said they also heard grenades exploding.
Other witnesses described it "like a Hollywood-action scene," said hospital volunteer Abiti Shah.
Mall customers crawled beneath cars in the parking lot and found cover in stairwells and a women's bathroom, presumably because the gunmen would be reluctant to look in that gender's restrooms.
Attackers went from store to store, taking hostages or randomly firing upon people. Gunmen asked customers whether they were Muslim. The terrorists apparently allowed people of that faith to escape from the mall.
The chaos included an unclear report on deaths. Finally, by day's end, 39 people were counted as killed -- a number that would grow.
Several hours into the terror assault, an al-Qaeda offshoot in neighboring Somalia called Al-Shabaab used its Twitter account to claim responsibility. Authorities now learned who they were dealing with, and the international community condemned the terror, including the Kenyan president whose nephew and his fiancée were among those killed.
Day Two: Sunday
The terrorists continued their siege of the mall, and confusion prevailed over the number of deaths and hostages.
Security forces decided to launch a "major assault" on the mall, police said.
As another violent day unfolded, "most of the hostages" were rescued, and security forces took control of "most parts" of the mall, the Kenyan military said.
Gunfire punctuated the day. Between the bullets are moments of silence. Soldiers surrounded the mall.
Authorities numbered the gunmen involved in the attack: 10 to 15 attackers. Further, unconfirmed reports emerged on who they could be: As many as three are from the United States, two are from Somalia and one each from Canada, Finland, Kenya and the United Kingdom. That information came from sources within Al-Shabaab who spoke to CNN about nine names published on Twitter who were purported to be the alleged hostage-takers.
CNN couldn't independently confirm that claim by Al-Shabaab.
"All efforts are underway to bring this matter to a speedy conclusion," the Kenyan military said.
Day Three: Monday
The first announcement about deaths on the other side of the siege is made: Three terrorists have been killed, authorities said.
So far, more than 200 civilians have been rescued, they added. But 11 Kenyan soldiers have been wounded, the military said.
Kenyan officials reassured the world that they were in control of the mall. The terrorists have little chance of escape, authorities said.
But sporadic gunfire sent aid workers and journalists running for cover. Inside the mall, the terrorists ignited a fire, spewing heavy smoke throughout the afternoon.
