Emotional protesters gathered at the Manhattan home of the United Nations secretary-general Friday morning to demand action on behalf of Israeli hostages held by Hamas and to accuse the UN of “legitimizing terrorism” through its inaction.

“What [has the UN] done, they’ve done nothing. In the most basic way, it’s legitimizing this situation. It’s legitimizing terrorism, legitimizing taking hostages,” organizer Omer Lubaton Granot told The Post after the peaceful demonstration.

Israel’s bombardment of Gaza entails “clear violations of international law,” according to the top United Nations official, who called for an “immediate ceasefire” as civilian casualties mount in the war against Hamas.

“Even war has rules,” U.N. Secretary-General Antonio Guterres said Tuesday morning. “Let me be clear: No party to an armed conflict is above international humanitarian law.”

In an alarming assessment, the head of the United Nations warned world leaders Tuesday that nations are “gridlocked in colossal global dysfunction” and aren’t ready or willing to tackle the challenges that threaten humanity’s future — and the planet’s. “Our world is in peril — and paralyzed,” he said.

The world is in "great peril, and paralyzed" United Nations (UN) Secretary-General Antonio Guterres warned the 77th session of the UN General Assembly kicked off on Tuesday.

After the COVID-19 pandemic restricted in-person attendance the previous two years, more than 150 heads of state and government were expected to attend the annual gathering in New York.

United Nations Secretary-General Antonio Guterres urged world leaders to increase taxes on coal, oil, and natural gas companies in order to mitigate the cost of climate change and provide relief from inflation.

“Today, I am calling on all developed economies to tax the windfall profits of fossil fuel companies,” Guterres said Tuesday. “Those funds should be redirected in two ways: to countries suffering loss and damage caused by the climate crisis, and to people struggling with rising food and energy prices.”
