Another survivor has been pulled from the rubble in Haiti two weeks after the island was hit by a devastating earthquake.
A crowd of looters pulled the man from the wreckage of a store that had been repeatedly raided and called for help from US soldiers, who treated him for a broken leg and severe dehydration.
Rico Dibrivell, 35, claimed he had been trapped since the earthquake.
The military provided no details about how he managed to survive, saying in a statement only that the man's family said he had been missing for two weeks.
More than 100 people have been unearthed by rescue teams since the January 12 quake, and many more by their neighbours, but most of those were in the immediate aftermath and authorities say it is unlikely for anyone to survive more than 72 hours without water.
On Saturday, an international team of rescuers unearthed a shop clerk who they believed had been buried since the earthquake.
Elsewhere concerns are growing for hundreds of thousands of hungry and thirsty children scattered among Port-au-Prince's squatter camps of survivors, without protection against disease or child predators, and often with nobody to care for them.
"There's an estimated one million unaccompanied or orphaned children or children who lost one parent," said Kate Conradt, a spokeswoman for the aid group Save the Children. "They are extremely vulnerable."
Ms Conradt said the group has helped some 6,000 children since the quake.
The UN children's agency, Unicef, has established a special tent camp for girls and boys separated from their parents in the quake, and who are in danger of falling prey to child traffickers and other abusers.
Save the Children has set up "Child Spaces" in 13 makeshift settlements, while the Red Cross and other groups are working to reunite families and get children into orphanages.
The post-quake needs of Haiti's children have outrun available help. Some youngsters have been released from hospitals with no one to care for them.
"Health workers are being advised to monitor and send separated/unaccompanied children to child-friendly spaces," the UN humanitarian office said in its latest situation report.
The "Child Spaces" are cordoned-off areas where children can play under supervision, and "run around being children, giving them a chance to return to normalcy as much as they can".
Such areas also protect children against the potential for abduction by child traffickers, a chronic problem in pre-quake Haiti, where thousands were handed over to other families into lives of domestic servitude, said Deb Barry, an emergency protection adviser with Save the Children.
She said her organisation is working to track down every rumour it hears about threats to stranded children, "but we haven't been able to verify those thus far".
Unicef spokeswoman Veronique Taveau said the organisation has been told of children disappearing from hospitals. "It's difficult to establish the reality," she said, but added that Unicef has strengthened security at hospitals and orphanages.
Save the Children, the Red Cross and other organisations are trying to establish a joint database of information to try to reunite separated families.
