The United Nations Relief and Works Agency for Palestine Refugees (UNRWA) said on Saturday that the Qalandia Vocational Training Centre, in occupied East Jerusalem, remains a United Nations facility and must be respected and protected under international law.
The statement came in response to the Israeli authorities' continued control of the site for a fifth consecutive day.
UNRWA said the facility had been damaged while under Israeli control and that it had received reports of individuals entering the premises and attempting to steal some of its contents.
The agency stressed the importance of protecting the centre and its property, citing its role in providing educational services and vocational training to Palestinian refugees.
UNRWA also strongly condemned Israeli actions at the Qalandia Training Centre on 25 August, including what it described as an intrusion and illegal activities on the premises.
"The Government of Israel is legally obligated to ensure that such actions are rolled back without delay and that they are prevented from recurring," UNRWA said.
The agency reiterated its commitment to fully resuming educational activities at the centre.
Israeli forces withdrew from the centre near Qalandia refugee camp and Kafr Aqab, north of Jerusalem, on Friday after raiding and taking control of the site since Tuesday.
However, the Israeli authorities have maintained control of the premises, with workers and a private security company remaining at the site.
Most entrances have been welded shut, surveillance cameras installed and models of soldiers placed inside, according to Omar Rajoub, Director of the Media and Information Department at the Palestinian Authority's Jerusalem Governorate.
Rajoub said the withdrawal of military forces did not amount to a full handover of the site, with Israeli authorities retaining control and the measures imposed inside the facility remaining in place.
He added that the steps appeared to be in preparation for projects announced by the Israeli municipality concerning the site.
