As the food crisis in Gaza continues to worsen, more than 100 global organizations have called on Israel to stop its strategy of "weaponizing" aid to Gaza. The organizations have signed a joint statement calling on Israel to do so.

Humanitarian aid agencies, including Oxfam and Médecins Sans Frontières (MSF), say they are constantly being told they will not be 'approved' to deliver aid unless they comply with Israel's strict rules.

Organizations that attempt to prove Israel is 'illegitimate' as a state or refuse to provide detailed information on Palestinian activists are at risk of being banned.

Israel has denied imposing restrictions on relief efforts, saying that the relief efforts, which are carried out in accordance with the rules introduced last March, are in line with Israel's "national interests."

The joint statement said that since March 2, most major international non-governmental organizations (NGOs) have not been able to send a single truckload of life-saving equipment to Gaza.

The organizations say that Israel has "rejected requests from dozens of private organizations to bring in life-saving supplies" under the pretext of the new rules. More than 60 such requests were rejected in July alone.

The statement said that as agencies failed to deliver aid, "hospitals lacked basic equipment; children, the disabled and the elderly are dying of starvation and preventable illnesses."

"ANERA has more than $7 million in life-saving supplies ready to go to Gaza. That includes 744 tons of rice, enough to make six million meals. But they are stuck just a few kilometers away in Ashdod," said Shane Carroll, CEO of American Near East Refugee Aid (ANERA).

Under new guidelines introduced in March, organizations must adhere to a new framework for maintaining registration in order to operate in Israel. It also includes conditions for canceling applications or revoking registration.

If Israeli authorities believe that an organization is denying Israel's democratic character or is conducting 'propaganda' against the country, the organization's registration may be revoked.

"Sadly, many aid agencies act as a cover for hostile and sometimes violent activities," Israeli Immigration Minister Amichai Chikli told AFP.

The minister also said, "Organizations that have no connection with hostile or violent activities and have no involvement in the boycott movement will be allowed to operate."

Oxfam policy lead Bushra Khalidi said Israel had blocked more than $2.5 million (about £1.8 million) worth of goods from entering Gaza.

Bushra Khalidi said, "This registration process is signaling to international NGOs that their ability to continue their activities may come at the cost of their freedom and ability to protest."

The warning comes as Israel intensifies its bombing of Gaza in preparation for a plan to take full control of Gaza City.

Israel says it will provide humanitarian aid to civilians "outside the war zone," but has not clarified whether the aid will be provided by the controversial Gaza Humanitarian Foundation (GHF), which is backed by Israel and the United States.

Israel also said the measure was necessary to prevent aid theft by Hamas, a charge Hamas has denied.

The United Nations said this month that 859 Palestinians have been killed near GHF installations since May, but the GHF has denied the death toll.
