Palestinian zoo worker Wael Abu Muhammed and visitors play with an ostrich at the 'Heaven of Birds and Animals Zoo' in Rafah, southern Gaza Strip, Wednesday, Aug. 6, 2008. Rafah's zoo, stocked almost entirely with smuggled animals, is a sign of Gaza's ever-expanding tunnel industry. Tunnel traders say dozens of passages snake the border and have become a mainstay of the local economy, with each passage feeding about 35 families.(AP Photo/ Adel Hana)

The problem is that they're not smuggling just exotic animals in those tunnels as this picture would have you believe.
