They are leaving Gaza via the Erez crossing and being transported to Jerusalem. The pilgrims are all over 60 years old.
When there, they may see this banner on top of the "religious" site, erected on Yom Kippur,
It says:
Our next war - the War of Independence.
The Islamic Movement in the Haram gives blessings to the Islamic nation in general, and our Islamic movement in Palestine in particular,
Because of the blessed Eid Al-adha, Allah will return to us and liberate us, and Al-Aqsa.
Allah accepts the obedient. Gaza won, and the truth won out over power!
