UN Secretary-General Antonio Guterres expressed concern Monday over the ongoing situation in the Gaza Strip, saying "nowhere is safe" in the besieged enclave.

"The extreme level of fighting and devastation in Gaza is incomprehensible and inexcusable...Everywhere is a potential killing zone," Guterres said on X.

It is high time for the parties to the conflict to show the political courage and political will to finally reach a deal, he added, Anadolu reported. 

Separately, Guterres spokesman Stephane Dujarric said the UN is calling on all parties to respect their obligations under international humanitarian law and to take constant care to “spare civilians and civilian objects.”

"I can further tell you that we and our humanitarian partners continue to assist families who are being displaced from northern Gaza to areas in the south," he told reporters.

Dujarric highlighted that the UN Office for the Coordination of Humanitarian Affairs (OCHA) has said that with each new evacuation directive, families in Gaza are being forced to make impossible choices: Stay amid active hostilities or flee to areas with little space or services.

"There is no safe place in Gaza. Not shelters, not hospitals, and not the so-called humanitarian zones," he stressed.
