After April 22, there were some 30,000–45,000 Arabs remaining in Haifa, from the pre conflict population estimate of 65,000–70,000. By mid-May there were only ~4,000. The displacement of Palestinians from Haifa formed a significant part of the larger
1948 Palestinian expulsion and flight. A number of historians consider the expulsions in Haifa and elsewhere to have been an instance of
ethnic cleansing. On 23April
Moshe Carmel declared
Martial Law in the town. On the same day units from the
Irgun moved into parts of downtown Haifa. Two days later the Haganah forced them to withdraw in a confrontation that resulted in some Irgun casualties. After the fall of the city there was widespread looting by Zionist forces in Arab areas.
Moshe Dayan was appointed to administer abandoned Arab property in the city. He instituted a policy of collecting anything the army could use and storing it in warehouses, with the rest distributed among Jewish agricultural settlements.
Golda Meir, who was consulted, agreed with this policy. Historian Adam Raz writes that "there is little difference in the way that Haifa and
Jaffa were plundered, because the two cities were completely pillaged." The military prosecutor for the Haifa district stated in mid-June that "there was no longer anything to take from the Arabs. It was simply a
pogrom. [...] The commanders, each one of them made excuses: ‘I only arrived two weeks ago’ etc. There was nobody to arrest. There was no way to know when the pillaging took place, and they replaced commanders daily."
David Ben-Gurion wrote in his diary that "There were cases where Haganah members, including commanders, were found in possession of stolen property too. About ten of them are currently being held for this." Historian
Saleh Abdel Jawad writes that "After the fall of Haifa, the Haganah continued to bombard civilian gatherings, especially near the port." He also relates that on 27 April, seven Palestinians accused of involvement in the
Haifa Oil Refinery massacre were executed by the Haganah. In July the remaining Palestinians were displaced from their homes and concentrated primarily in the
Wadi Nisnas neighbourhood in a process of
ghettoization. Adam Raz writes that Haifa's remaining Arab Christians were to be concentrated in Wasi Nisnas and the Arab Muslims in
Wadi Salib. Raz writes that this was ordered by David Ben-Gurion and that further orders were given that it was "forbidden for the number of the Arabs in the city to exceed 15,000; second, two-thirds of those who remained would be Christians and one-third would be Muslim". A systematic destruction of what had been Arab housing was implemented in certain areas by Haifa's Technical and Urban Development departments in cooperation with the IDF's city commander Ya'akov Lublini. ==Historiography==
