United Nations Secretary-General Antonio Guterres on Monday called for a truce in Israel’s war on Gaza.

He also called for the removal of "all obstacles to ensure the delivery of lifesaving aid at the speed and massive scale required" to Gaza, where the UN has warned that a quarter of the population are on the brink of famine, Reuters reported. 

"International humanitarian law lies in tatters," he told reporters. "And a threatened Israeli assault on Rafah could plummet the people of Gaza into an even deeper circle of hell."
