It was never formally annexed to Egypt, 1845183066Sedwin# though. 1846183066Sedwin# 1847183066Sedwin# The rest of Palestine was under Jordanian rule at that time, formally 1848183066Sedwin# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 1849183066Sedwin# the country's previous name of "the Hashemite Kingdom of the 1850183066Sedwin# Trans-Jordan"). So the rules for Jordan for that time apply. Major 1851183066Sedwin# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 1852183066Sedwin# East Jerusalem. 1853183066Sedwin# 1854183066Sedwin# Both areas were occupied by Israel in June 1967, but not annexed (except 1855191052Sedwin# for East Jerusalem).
