It was never formally annexed to Egypt, 1941# though. 1942# 1943# The rest of Palestine was under Jordanian rule at that time, formally 1944# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 1945# the country's previous name of "the Hashemite Kingdom of the 1946# Trans-Jordan"). So the rules for Jordan for that time apply. Major 1947# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 1948# East Jerusalem. 1949# 1950# Both areas were occupied by Israel in June 1967, but not annexed (except 1951# for East Jerusalem).
