Bush daughter in Peru for UN program

LIMA: Jenna Bush, one of President George W. Bush's twin daughters, arrived in Peru on Saturday to work with UN children's assistance programs, United Nations officials said.   

Bush, 26, was greeted by UN, UNICEF and US embassy officials after landing on a commercial flight amid tight security measures.   

Jenna Bush, who taught at an elementary school in Washington, has written a book, 'Ana's Story: A Journey of Hope', based on her experiences working as an intern for UNICEF in Latin America.   

During her trip, she plans to visit the Inca citadel of Machu Picchu and various Peruvian cities, said a UN source who welcomed the US president's daughter.
