The zoo was decimated during the 2003 U.S.-led invasion, when the staff fled and looters gutted the zoo and the park surrounding it. Only a handful of animals survived, and later the grounds were used as a holding facility for looters detained by U.S. soldiers. The zoo reopened in July 2003 after being rehabilitated under the care of U.S. Army Capt. William Sumner and South African conservationist Lawrence Anthony. Today, it houses more than 1,000 animals and is a popular destination for families.

Samad and Dina Jabbo dance at a banquet organized for the Iraqi community in El Cajon, Calif. Samad, 40, his wife Dina, 37, and their daughters Monica, 16, and Milano, 12, and son Antonio, 7 months, arrived in the United States in June 2010 after living in Damascus, Syria, for four years. They are Christians from Baghdad and have green cards. They felt their lives were in danger when they lived in Iraq.

Monica Jabbo opens her locker at school in El Cajon. She and her sister Milano love being in the U.S. but it's still a struggle for the family -- they have to finance day-to-day life and pay their rent, which is $1,200. Because Monica's father Samad is unemployed, the family has to rely heavily on government assistance -- $760 per month.

The Baghdad cafe in El Cajon, above, is a popular tea house frequented by many Iraqis in the community.

Mohammed Mustafa, 68, in his store in El Cajon. Mustafa and his wife Nasrin, 58, have eight children, two of whom live at home. They are from Dohok in Iraqi Kurdistan. In August 1988 they fled to Diyarbakir in Turkish Kurdistan, and in September 1991 they arrived in New York. They made their way to El Cajon in June 1993. Mustafa feels he has made a mistake by coming to the U.S. and not returning to Kurdistan, where the economy nowadays is growing. The family recently opened this 'Community Fashion' store but business is very slow, he says.

Breakfast at home. Khattab Aljubori, 37, and his wife Suhad, 31, frequently speak to their family in Iraq through Skype. The computer is parked near the table so that they can have breakfast 'together'. The family, including children Ibrahim, 4, Awos, 3, and twins Mustafa and Fatima, 6 months, as well as Khattab's mother Nhanaa, 61, came to San Diego in November 2010 from Babylon, Iraq. Khattab worked for the U.S. in Iraq as a computer and info system administrator and was often threatened for being a U.S. agent. In the end it became so dangerous for him and his family that they sought asylum in the U.S. and were granted visas.

Khattab likes the U.S. but his wife wants to go back to Iraq. She says she feels locked up and misses her family. Finances are also an issue -- Khattab earns some money repairing people's computers but they depend on government support and sometimes find it difficult to pay the rent.
