UN Secretary General Antonio Guterres has made a renewed call for an immediate ceasefire in Gaza.
"It is time to silence the guns," he said, speaking from the Egyptian side of the Rafah crossing with the enclave.
He also called on Israel to give "total, unfettered" access to humanitarian goods throughout Gaza.
A UN-backed food security assessment this week said 1.1 million people in Gaza were struggling with catastrophic hunger and starvation.
