Guterres raises the legal issues that the new Israeli laws raise, according to the UN spokesperson Stéphane Dujarric. The laws will have a "devastating impact on the humanitarian situation for Palestinians in occupied territory", he adds.
The Israeli parliament, the Knesset, voted through the new legislation, which consists of two parts, on Monday.
Norway will take an initiative in the UN to clarify whether Israel's ban on the UN agency Unrwa is a violation of international law.
We want a legal clarification of Israel's obligation to facilitate humanitarian aid to people living in the occupied areas of Gaza and the West Bank, says Norway's Foreign Minister Espen Barth Eide (Ap) to VG.
Ireland's Prime Minister Simon Harris is simultaneously urging the EU to review trade relations with Israel following the country's decision to ban Unrwa.
Harris calls the decision "shameful".
The most important thing the EU can do right now is to review trade relations, says Harris ahead of a meeting with EU Council President António Costa.
According to Harris, there is no alternative to Unrwa, and Israel's new legislation, which prevents the UN agency from operating, will lead to more people dying.
