UNITED NATIONS (AP) The U.S. vetoed a U.N. resolution Wednesday to condemn all violence against civilians in the Israel-Hamas war and to urge humanitarian aid to Palestinians in Gaza, saying it was too early to craft an appropriate Security Council response to the crisis.

U.S. Ambassador Linda Thomas-Greenfield said the council needs to allow current diplomatic efforts, including by President Joe Biden , to unfold and to find out more facts on the ground first. She also criticized the measure for failing to underline Israels right to self-defense.

The resolution sponsored by Brazil had wide support and would have condemned all violence against civilians, including the heinous terrorists attacks by Hamas against Israel. The vote in the 15-member Security Council was 12 votes in favor and the U.S. against, with Russia and Britain abstaining.

Thomas-Greenfield said that Biden was in the region engaging in diplomacy hoping to protect civilians, secure the release of hostage and prevent the conflict from spreading. We need to let that diplomacy play out, she said.

She said the Security Council must speak out, but should be informed by facts on the ground and support direct diplomacy efforts that can save lives the council needs to get this right.

The American ambassador criticized the resolution for not saying anything about Israels right to self-defense following Hamas surprise Oct. 7 attacks that killed more than 1,400 people in Israel. Since then, the Gaza Health Ministry says nearly 3,500 people have been killed in Gaza and more than 12,000 wounded.

Britains U.N. Ambassador Barbara Woodward also criticized the resolutions failure to mention Israels right to self-defense.

The voting and debate followed Tuesdays huge explosion and fire at a Gaza City hospital packed with patients, relatives and Palestinians seeking shelter, in which the hospital said hundreds of people died. Hamas said it was from an Israeli airstrike, while Israel blamed a misfired rocket by the Palestinian militant group Islamic Jihad. Islamic Jihad denied any involvement.

Council members rejected two proposed Russian amendments to the resolution, which failed to get the minimum nine yes votes. One called for a humanitarian cease-fire and the other would condemn indiscriminate attacks on civilians and civilian objects in Gaza, which include hospitals and schools.

Russias U.N. Ambassador Vassily Nebenzia said the Brazil resolution, which called for humanitarian pauses to deliver aid, wouldnt have helped to avoid Tuesdays explosion at the Gaza hospital. It is only a cease-fire that will help to do this, he said.

He told council members who abstained or opposed the Russian amendments the U.S. voted against both that they will have to bear responsibility for what happens now to people in their own countries, the region, and the people who are living under this deadly threat.

Nebenzia accused the United States of hypocrisy and double standards, saying the Americans didnt want a solution in the Security Council.

Brazils U.N. Ambassador Srgio Frana Danese, the current council president, called the defeated resolution robust and balanced. stressing that it also called for the immediate release of all hostages, protection of civilians in Gaza from forced relocation, and the ethical necessity to provide them with food, fuel, water and medicine.

Sadly, very sadly, the council was yet again unable to adopt a resolution on the Israeli-Palestinian conflict, he said. Council paralysis in the face of a humanitarian catastrophe is not in the interest of the international community.

France, China, the United Arab Emirates, the Arab representative on the Security Council, and many other council members also expressed regret and disappointment at the U.S. veto.

The divided Security Council has been even more polarized since Russia invaded Ukraine in February 2022, and the votes on the Brazil resolution reflected the divisions.

Immediately after Tuesdays votes and speeches, the council started an emergency meeting called for by Russia, the United Arab Emirates and China to discuss the Gaza hospital blast.

The councils actions took place amid frantic diplomatic efforts to prevent the Israeli-Hamas conflict from spreading, including Bidens lightning trip to Israel where he met with Prime Minister Benjamin Netanyahu.

U.N. humanitarian chief Martin Griffiths noted in a video briefing from Doha, Quatar, that Tuesdays massive explosion deprived Gaza of a hospital that cared for more than 45,000 patients a year.

After the hospital blast, Palestinian President Mahmoud Abbas backed out of a meeting with Biden, Egyptian President Abdel Fattah el-Sissi and King Abdullah II of Jordan, leading the Jordanians to cancel the meeting,

The 22-member Arab Group at the United Nations expressed outrage at the hospital deaths and called for an immediate cease-fire to avoid further Palestinian casualties and the opening of a corridor to safely deliver aid to millions in Gaza.

Egypts U.N. ambassador, Osama Mahmoud, told reporters that a summit will take place Saturday in Cairo as scheduled with regional leaders and U.N. Secretary-General Antonio Guterres. The five permanent Security Council nations are also invited, he said.

Mahmoud said the summit will address the humanitarian crisis sparked by the Israeli-Palestinian conflict, how to achieve a cease-fire, and whether any serious attempt to have a political horizon exists to tackle the issues blocking an Israeli-Palestinian peace agreement.

U.N. Mideast envoy Tor Wennesland told the emergency council meeting, I fear that we are at the brink of a deep and dangerous abyss that could change the trajectory of the Israeli-Palestinian conflict, if not of the Middle East as a whole.

After a century of conflict and half a century of Israeli occupation, he said the international community has failed collectively to help Israel and the Palestinians reach a political settlement. And he warned that events following the Hamas attacks have served to re-ignite grievances and re-animate alliances across the region.

Wennesland said the immediate objectives must be unrestricted humanitarian access to Gaza and freeing the hostages followed by collective action to end the hostilities and prevent an expansion of the conflict. Beyond that, he said, there must be an international effort to find a political horizon to end the Israeli-Palestinian conflict not a patchwork of temporary fixes.
