Exclusive video shows chaos of Kenya mall attack

>>>
is all over now, the siege inside the upscale
shopping mall
in
nairobi
,
kenya
has finally been put down. it attracted the attention and of course the sadness of people around the world. the kenyan government puts the
death toll
at 61 civilians and six members of their own
security force
. they have cautioned the
death toll
may rise because there was a collapse inside the security structure, and there is the possibility more bodies could be discovered. well, tonight we have a look at the height of it in the mall, and we just heard from an
american woman
back in the country today after havisurviving the attack. we begin tonight with
ron allen
, good evening.

good evening, brian,
kenyan president
said that 11 were captured, and couldn't confirm that americans were among them. tonight, we have new video of the first terrifying moments after the attack. inside the
west gate
mall saturday,
security forces
respond to the attack, helping shoppers escape, hands in the air to show they are unarmed. it is eerily quiet, the music playing in the mall, the american singer, bruno mars. a family,
playing dead
to avoid harm, afraid to move. a
plain clothes
officer reaches them and reassures them. carrying the child, he helps them to safety. this morning, three days after the attack, government forces searched for any remaining militants. a mop-up operation, they called it, after days of terror. late today,
kenya
's president addressed the nation.

>>
we have been badly hurt and feel great pain and loss. but we have been brave, united and strong.
kenya
has stared down evil and triumphed.

>> reporter:
triumphed, but at a terrible cost, more than 60 dead, some unaccounted in the mall, where three floors collapsed during the government operation to re-take the four-story complex. the mall in part is israeli owned, with
high end
movie theaters and high-priced shops, nike and bose. it was long seen as a terrorist possibility. using two entrances, opening fire and locking themselves in a supermarket,
amateur video
captured the terrified shoppers there running for cover. one man hid in a store for four histories, texting her brother outside, who told the rescue crews where to find her brother.

>>
i am praying the entire time.

>> reporter:
images of fear athey did not want the city to see.
nairobi
relies on terrorism, and diplomatics here. they are eager to try to convince the
outside world
the situation is well in hand. this dutch nurse was killed with her boyfriend. she worked for the
clinton foundation
and was remembered today by the former president.

>>
they went to
nairobi
because they thought it was the safest place for her to give birth, and they were just walking in the mall that day. and they were both killed along with the child.

>> reporter:
in
nairobi
, the funerals have begun, including this one for a 16-year-old girl.

>>
there is no word to express what we are going through. we are deeply saddened by what has happened to every person, every family who has gone through this.

>> reporter:
and as this nation begins three days of official mourning, many questions remain. what happened to the hostages? were they all rescued or did some terrorist join the effort to free them? the president did not say.
