SARAH SMITH: The flames are consuming what's left of the Church of the Perpetual. What wasn't destroyed by the earthquake and aftershocks will be taken by arson. A violent aftershock at dawn terrified people who are already deeply traumatized. It felt like another large quake.
WOMAN: It was like the first time.
SARAH SMITH: And that must make people very afraid.
WOMAN: Yes, they was. They was very afraid. They was very afraid. So, my mom crying, because she think it will be the same thing like the first time. She was very afraid.
SARAH SMITH: Thousands of people are living on the streets because they have to. They have nowhere else to go. But others chose to sleep out here.
Some of the houses are still standing, so why are people still sleeping in the streets?
MAN: So, they -- they -- they fear. They are very scared of the house, because, every time there is the -- the land is shaking. So, they are very, very, very, very scared.
SARAH SMITH: Most people say they have no idea where to go and find the aid that is now getting to parts of the city, one million rations delivered in the last week, but three million people need food and water daily.
You can tell from the litter around here that some food aid is getting through. This wrapper for a humanitarian daily ration says it's a food gift from the people of the United States of America. But getting this through once isn't enough. The people here need to be fed every day, and they're going to need it for a very long time to come.
When water does arrive, it can cause chaos. Desperate people try to grab what they can, even grabbing it from each other. The weak will go thirsty.
So, how careful do you have to be about security? Are there problems when people are handing out aid?
COLIN CHAPERON, American Red Cross: There is. I mean, we have to really -- our teams go in, and they try to sensitize a community, just basically let them know that we can't distribute to everybody at one time, that the assessments are ongoing, that distributions will happen over time.
SARAH SMITH: Weapons are appearing on the street, too, fights breaking out over pretty meager supplies. And the threat of more serious violence hangs in air.
By night, Port-au-Prince is a frightening dystopian vision. People with nowhere to go walk down dark streets past the burning remains of their ruined city. Then, out of the darkness walks a miracle, Satina Juacoyn, closely followed by her 8-year-old brother, Moses.Triumphantly rescued after a week trapped within their family house.
