"Let me be clear: There is simply no alternative to UNRWA," the United Nations Relief and Works Agency for Palestine Refugees in the Near East, Tedros Adhanom Ghebreyesus said in a video posted on X, AFP reported.
"This ban will not make Israel safer. It will only deepen the suffering of the people of Gaza and increase the risk of disease outbreaks," Tedros added.
His comments came after Israel said it had formally notified the UN of its decision to sever ties with UNRWA after Israeli lawmakers backed the move last week.
The suspension of the agency, which coordinates nearly all aid in war-ravaged Gaza, sparked global condemnation including from key Israeli backer the United States.
The move is expected to come into force in late January, with the UN Security Council warning it would have severe consequences for millions of Palestinians.
