Cash cow: A confused-looking bovine is lowered into an underground chamber in Rafah on Nov. 15. Recently, livestock smuggling has climbed as Muslims prepare for Eid al-Adha, in early December, during which animals are slaughtered in commemoration of Abraham’s willingness to sacrifice his son for God. In October, calves at one tunnel cost $600 each: $350 for the animal and $250 for the passage. Such smuggling is lucrative for smugglers and Hamas, which in October started collecting a $2,500 yearly license fee from tunnel owners.
