The United Nations Security Council on Thursday offered its full support to Secretary-General Antonio Guterres, after Israel said he was “persona non grata” for not initially condemning Iran’s massive ballistic missile attack.

Without naming Israel, the council’s five permanent members — Britain, China, France, Russia and the United States — and the 10 non-permanent members “underscored the need for all member states to have a productive and effective relationship with the secretary-general.”

The Council also asked member states to “refrain from any actions that undermine his work and that of his office.”

“Any decision not to engage with the UN secretary-general or the United Nations is counterproductive, especially in the context of escalating tensions in the Middle East,” it said.

Israel on Wednesday declared the UN leader persona non grata for failing to specifically condemn Iran’s missile attack on Israel in initial comments that highlighted the “broadening conflict in the Middle East” without mentioning the Iranian assault. He did later condemn Iran’s missile barrage.

Israel has long had strained relations with the United Nations, with ties between the state and the international body souring even more after the October 7 Hamas attacks on Israel.

France on Thursday condemned Israel’s decision, saying it was “unjustified.”

“France regrets the unjustified, serious and counterproductive decision taken by Israel to declare the secretary-general of the United Nations, Mr. Antonio Guterres, persona non grata,” the French foreign ministry said in a statement.

Paris said it had “full support for and confidence” in Guterres, adding that the United Nations played “a fundamental role in the stability of the region.”

The United States has already criticized the move by its ally. And EU foreign affairs chief Josep Borrell also defended Guterres in a speech in Pontevedra in his native Spain saying that “attacks on the UN secretary-general” must be rejected.

“Yes, everything started with the terrorist attacks by Hamas that we condemn, but these attacks, as the UN secretary-general has said, didn’t come from nowhere,” Borrell declared, echoing remarks Guterres made weeks after the October 7 terror onslaught that prompted Israeli calls for his resignation.

The attacks were “the umpteenth chapter of, a long story that started before,” Borrell went on.

“To say that should not mean someone being called or given the insult of being antisemitic,” he said. “This word should not be trivialized… it is too serious, too painful to be applied to someone who expresses an opinion different from that of a government.”

Borrell said Israel has the right to defend itself “but this right, like all rights, has limits.”

“The question that we, Europeans, do not want to ask ourselves, or at least do not want to answer, is whether these limits have been reached. My answer is yes, unfortunately,” he said.
