The UNWRA does not define refugees. They only define who qualifies for aid.Sorry Challenger but your consistent inability to address any of the points presented isn't very convincing.
Happy to address a point once you make one worth addressing.
UNWRA is irrelevant to resolving who is indigenous to Palestine, but that said, the refugees UNWRA deals with nevertheless have a much greater claim to being indigenous than the Russians, Poles, Hungarians and other Eastern Europeans who came over on the boat in the 20th century.
The UNWRA does define who are Palestinians refugees and they pass the data on to the UN. This results in the UN allocating so much money to the UNWRA. The UN sets the criteria for refugee status, and one of those is 2 years residency in the country, because 90% of the alleged refugees were arrivals in the 1947 to 1949 time slot they did not meet the UN crir=teria and so UNWRA was formed. No other group has access to UNWRA funds and help but Palestinian muslims.
