Transcript for Cleanup effort underway after deadly Colombia landslide

Turning to the search for survivors in Colombia after that catastrophic landslide left more than 250 people dead. A major rescue and cleanup effort is under way and our chief national correspondent Tom llamas is on the ground in mocoa, Colombia, with the latest. Good morning, Tom. Reporter: Amy, good morning to you. We've been reporting about that wall of water. I wanted to show you how high it came. This is one of the rivers that overflowed. It actually came over that bridge and wiped out this entire neighborhood. Now, everyone here in mocoa is wearing these surgical masks and you have to because the air quality here is so poor from all of the dust of the destruction and, of course, it's mixing with this unbearable stench from the loss of life. This morning emergency teams digging through neighborhoods buried in mud. At this pnt the chance of finding any survivors is growing slim. Hundreds are dead and the number is still rising in this devastated Colombian town and floodwaters and debris crashing down in an avalanche taking residents by surprise. Outside the town cemetery we saw scores of residents lined up to find out if their loved ones were among the dead. This woman in tears after identifying the body of her sister. But still no sign of her 11-year-old niece, last seen running from the wall of water and desperation is now growing as hundreds are displaced. Inside the largest shelter here we saw the overflow of people needing help. The competition to get food and several families left homeless. People sleeping wherever they can. One of the first things you notice is the amount of children everywhere running around being fed. But many of them have been orphaned by this disaster. Colombia's president says his next fear for them a public health crisis because so many are getting by with so little. Now, the president tells us he spoke with president trump yesterday over the telephone who offered assistance. President Santos says what Colombia needs is food. They need diapers and they need bedding. The red cross here in Colombia is coordinating all of those efforts. What a tragic situation. Okay, Tom, thanks very much.
