My source is Billye Brim Ministries. Billye regularly travels to Israel and speaks Hebrew. She got this information from Palestinian Christians. It must be Fatah or Hamas who run these camps.
And .. there is no way my statements conform to your premise, "but it has a bit of the 'Jews drink the blood of Christian babies on Passover' ring to it".
These teachings come straight from Islamic holy books and teachings..
It is taught that every animal, bird, serpent, plant, rock, should aspire to betraying the jew so that the True Muslim can find and kill them..
The "suras" from the Koran have been quoted countless times on various threads, and should be common knowledge by now to anyone that frequents these posts.
Asking for a "source" on this is a bit weak on that point alone..
The lessons being taught to the children are simple extensions of the Suras..
