The head of UNICEF warned Tuesday that people may still be trying to smuggle children out of Haiti and said protecting youngsters who survived the earthquake is the top concern of the U.N. children's agency.
Ann Veneman said in an interview with The Associated Press that UNICEF is starting a program to identify children who lost or can't find their parents. The group is also working with other groups to put children who are alone into facilities where they can receive food, water and psychological help, she said.
"This is a children's emergency," she said.
Veneman, who visited Haiti last week, said in every humanitarian crisis there's a risk that children will be trafficked out of the country for sexual exploitation, adoption, child labor or other illegal purposes. In Haiti, she said, "this is a big concern."
Last week, 10 Americans were charged with kidnapping and criminal association for trying to take 33 children into the neighboring Dominican Republic on Jan. 29 without proper documentation. The Baptist missionaries say they were heading to a Dominican orphanage following Haiti's devastating quake, and had only good intentions.
Veneman said UNICEF has learned of some other instances "where there is concern that children may not have (had) the necessary documents when they left."
At the airport in Port-au-Prince and the border with the Dominican Republic, specially trained officials are now checking documents, which Veneman said should make a difference.
Veneman declined to comment on the detained Americans, saying the judicial system in Haiti is handling the case: "I think we need to await the outcome of those proceedings," she said.
Veneman said Haitian Prime Minister Jean-Max Bellerive expressed concern at the massive media attention directed at the detained Americans.
"As the prime minister said to me in a meeting with him, `I spend so much of my time answering questions about these 10 Americans when I have 2 million people in need here,"' the UNICEF chief said,
Even before the Americans were detained, fears that child traffickers would take advantage of the chaos following the quake led Bellerive to announce that all foreign adoptions would need his personal approval.
Veneman said there is no estimate of the number of children left alone as a result of the Jan. 12 quake. Before it struck, there were between 300,000 and 350,000 children in residential care facilities but many were left by parents too poor to take care of them, she said.
Veneman said some care facilities and orphanages collapsed in the quake, killing children, though nobody has any figures.
Many children lost their parents, and most have now been put "into some kind of safe place," including residential care facilities like an SOS children's village, she said.
"The primary concern is protection of children making sure they have shelter, food, water, the basic necessities and care," Veneman said.
UNICEF has begun a program to to give children some kind of identity such as an arm band to make sure that as the process goes through they can then reunite them with family members.
"This is really the goal, to reunite any unaccompanied children with family members," she said.
According to population estimates, 38 percent of Haiti's nine million people are under the age of 15 and about 45 percent are 18 and under, Veneman said.
