ASUNCION, Paraguay ? President Bush’s daughter Jenna came to this poor, landlocked South American country to take part in a UNICEF program for young professionals volunteers, the U.N. children’s fund said Monday.

UNICEF released few details about the program involving the 24-year-old, citing security concerns. She is planning to stay in the country for 10 days.

“The visit is strictly private in nature,” UNICEF said in a one-page statement released by spokeswoman Natalie Echague. “She will get to know the UNICEF activities in Paraguay and some of the programs it cooperates in.”

Jenna Bush planned no news conferences and no interviews, according to UNICEF.

Paraguay, with 6 million people, is one of the poorest countries in South America.
