Residents of Haiti's capital Port-au-Prince have been searching through the wreckage of their homes, trying to find friends and relatives. Many were buried as buildings collapsed during Tuesday's earthquake.

With their bare hands, volunteers dig through the rubble to free people buried underneath.

Port-Au-Prince resident Monnos Naol said, "I need somebody, I need somebody, because if this he can't stay here, he can't stay here. He dead."

Some of the injured were being evacuated by plane.

Dominique, relative of girl being evacuated, said, "It's my niece, my daughter that needed to be evacuated, and among all the problem that we have, I do have my small, little problem also. Thank God she is going and I really appreciate the people that helped me."

Authorities believe 3-million people, or a third of Haiti's population, may need emergency relief.

Port-Au-Prince resident Pierre Liesco said, "Going to be very hard for us, because what we have for now, we can use it for a while, for two or three days. I think in the next few days people are going to be running out of food, out of water. I think we need help because it's urgent."

The courtyard of the capital's General Hospital has been turned into a makeshift ward. Countless patients and their families huddle together on mattresses and temporary beds.

Hospital manager Guy Laroche said, "Everything is wrong now, everything is wrong now. You know we have nothing, nothing, nothing because the employer of the hospital has a problem at home. They've got to fix the problem at home before to come here to work."

A World Health Organization spokesman said, severe damage to at least 8 Port-au-Prince hospitals has made it nearly impossible to treat many of the injured. They're now struggling to prevent the outbreak of disease.
