Next we head overseas to the philippines where tonight families are struggling to survive, desperate for food, water, shelter. Help from around the world is trickling but the slow pace is testing the human spirit. Terry moran is there. Reporter: The people are are nearing the breaking point. People of the world, please, come here. We need you. Reporter: I'm talking down one of the main roads in tacloban. It used to be fine houses and shops.

The children, the most vulnerable. At the shattered tacloban hospital, a mother cradled her dead infant. I just told my baby I am sorry, she says.

Right now still the fastest most effective way is what they're doing here, bringing clean water in on huge pallets. There is no time to lose and so much at stake. But the good news to report today here at the airport is the pace is picking up. It's a 24-hour operation. Planes coming in and out and the aid is really starting to flow. Food, clothing, water for a people in crises. Diane? That is good news, finally starting to flow, thank you, terry more on.
