The disputed, American and Israeli-supported Gaza relief foundation announces it is winding down its humanitarian work in the Gaza region, after almost six months.
The foundation had already suspended its several relief locations in Gaza following the halt in hostilities between Palestinian factions and Israel took effect recently.
The foundation sought to avoid UN systems as the main supplier of relief to Palestinian residents.
International relief agencies would not collaborate with its system, stating it was questionable and hazardous.
Hundreds of Palestinians were fatally wounded while attempting to obtain sustenance amid chaotic scenes near the organization's distribution points, mainly through Israeli military action, based on UN documentation.
Israeli authorities stated its troops fired alerting fire.
The organization declared on Monday that it was terminating work now because of the "successful completion of its crisis response", with a total of three million packages containing the amounting to in excess of 187 million sustenance units distributed to Gazans.
The organization's top administrator, the foundation leader, also said the American-directed Civil-Military Coordination Center - which has been created to help implement US President Donald Trump's Gaza peace plan - would be "taking over and developing the system the foundation tested".
"GHF's model, in which militant groups were prevented from misappropriating relief supplies, had major impact in convincing militant groups to participate and securing a halt in hostilities."
The militant group - which disputes allegations of misappropriation - supported the shutdown of the aid organization, according to reports.
A spokesman for stated the organization should be made responsible for the harm it caused to Palestinians.
"We request all worldwide humanitarian bodies to make certain that consequences are faced after leading to casualties and wounds of many residents and covering up the nutritional restriction approach employed by the Israel's administration."
The organization commenced activities in Gaza on May 26th, a seven days following Israeli authorities had somewhat relaxed a total blockade on aid and commercial deliveries to Gaza that lasted 11 weeks and caused severe shortages of essential supplies.
Subsequently, a nutritional emergency was proclaimed in the Gaza metropolitan area.
The GHF's food distribution sites in the southern and middle regions of Gaza were operated by US private security contractors and positioned in regions under Israeli military authority.
International organizations and their affiliates said the methodology violated the fundamental humanitarian principles of neutrality, impartiality and independence, and that channelling desperate people into military-controlled areas was inherently unsafe.
United Nations human rights division reported it tracked the fatalities of no fewer than 859 Gazans seeking food in the proximity to foundation locations between spring and summer months.
A further 514 persons were fatally wounded around the routes of UN and other aid convoys, it further stated.
The majority of these individuals were fatally wounded by the Israeli forces, as per the organization's documentation.
The Israeli military claimed its soldiers had released alerting fire at individuals who came near them in a "threatening" way.
The organization declared there were no firearm incidents at the aid sites and claimed the international organization of using "untrue and confusing" figures from Gaza's Hamas-run health ministry.
The organization's continuation had been indefinite since Hamas and Israel agreed a ceasefire deal to implement the primary segment of the American administration's peace initiative.
The arrangement specified humanitarian assistance would take place "free from intervention from the involved factions through the international bodies and their affiliates, and the international relief society, in addition to other worldwide bodies not associated in any manner" with Hamas and Israel.
United Nations representative the international body's communicator said on Monday that the foundation's closure would have "zero effect" on its activities "as we never partnered with them".
He also said that while more aid was getting into Gaza since the ceasefire took effect on early October, it was "inadequate to meet all the needs" of the 2.1 million residents.
