A group of 22 countries and senior European officials on Monday voiced deep concern over Israel’s top court rejecting an appeal by international non-governmental organizations (INGOs) against a controversial registration law, warning that the measure could severely undermine humanitarian operations in the occupied Palestinian territories, Anadolu Agency reports.

In a joint statement, the signatories said the recent decision by the Israeli High Court to uphold the law would “affect and severely limit” the ability of INGOs to operate in the Occupied Palestinian Territory, including East Jerusalem.

“The recent decision by the Israeli High Court to reject the INGOs’ appeal regarding the registration law is deeply concerning,” the statement said.

The countries urged Israel not to implement the legislation in its current form, arguing that it would further restrict humanitarian actors already struggling to respond to immense needs in Gaza and the occupied West Bank.

According to the statement, international NGOs play a critical role in delivering essential services alongside Palestinian civil society organizations and UN agencies, including in sectors such as water, sanitation, healthcare, education, nutrition and demining.
