RAFAH, GAZA STRIP - NOVEMBER 15:  A cow is lowered into an underground chamber as Palestinians continue to smuggle supplies and animals through tunnels between Rafah, southern Gaza Strip and Egypt as the Gaza crossings remain closed on November 15, 2008 in Rafah, Southern Gaza Strip, Gaza. Israel has tightened the blockade in recent weeks as a response to continued rocket fire by Palestinian militants and assertions on both sides that ceasefire agreements have been violated. Muslims are preparing for Eid al-Adha, celebrated at the end of pilgrimage of the Hajj, purchasing cattle to be slaughtered in commemoration of Abraham's willingness to sacrifice his son for God.
