There is no state of Palestine and so there are no "citizens" of such.
Perhaps Arabs who are citizens?
After all, there are still Jews who have their Palestinian passports from the pre-1946 period.
I am referring to this from a mixed-upIs Ben-Gurion University:-
BGU researchers complete major study of Palestinian relations on both sides of the fence^
While both groups look to bolster connections, different identities evolve
BEER-SHEVA, Israel, September 4, 2012 – A new wide-scale study of relations between Palestinians who are citizens of Israel and Palestinians living in the West Bank, conducted by Ben-Gurion University of the Negev researchers, has found that while the dominant strategy is to strengthen ties, Palestinian citizens of Israel (’48 Arabs) are more likely to embrace their own narrative and retain some distance from Palestinians living in the West Bank (’67 Arabs).
...[ Prof. Shifra] Sagy and her team discovered that there was relatively low acceptance of the “other’s” narrative, particularly among Israeli Arabs. There were also high levels of anger and less empathy towards the ’67 Arabs and vice versa.
...The survey was conducted as part of a joint project between Israelis, Palestinians and Germans funded by the German research foundation DFG.
