Lost children database goes live
Children separated from families after the deadly Hurricane Katrina are being helped by the US National Center for Missing and Exploited Children (NCMEC).
It helps prevent child abduction and sexual exploitation and usually runs a CyberTipline to report net abuse.
It has now set up a Katrina Missing Persons Hotline and its website is also serving as an online album of children who are trying to find their families.
Rescue teams are still hunting for survivors in New Orleans.
There are thought to be several thousand still in the city, but they have been urged to leave while the massive clean-up operation starts.
