[Q]: Passage: Ashkelon was formally granted to Israel in the 1949 Armistice Agreements. Re-population of the recently vacated Arab dwellings by Jews had been official policy since at least December 1948, but the process began slowly.

These early immigrants were mostly from Yemen, North Africa, and Europe. During 1949, the town was renamed Migdal Gaza, and then Migdal Gad. Soon afterwards it became Migdal Ashkelon. The city began to expand as the population grew. In 1951, the neighborhood of Afridar was established for Jewish immigrants from South Africa, and in 1953 it was incorporated into the city.
