It was never formally annexed to Egypt, 1487# though. 1488# 1489# The rest of Palestine was under Jordanian rule at that time, formally 1490# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 1491# the country's previous name of "the Hashemite Kingdom of the 1492# Trans-Jordan"). So the rules for Jordan for that time apply. Major 1493# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 1494# East Jerusalem. 1495# 1496# Both areas were occupied by Israel in June 1967, but not annexed (except 1497# for East Jerusalem).
