The US has for the sixth time vetoed a draft resolution at the United Nations Security Council that would have demanded an immediate and permanent ceasefire in Gaza and the release of hostages.

US deputy Middle East envoy Morgan Ortagus said the text did not go far enough in condemning Hamas or recognize Israel's right to defend itself.

All 14 other members of the Security Council voted in favor of the draft resolution - which described the humanitarian situation in Gaza as catastrophic and called on Israel to lift all aid restrictions.

This veto comes as the UN's humanitarian office warns that the last lifelines for civilians are collapsing in Gaza City as Israel expands its military offensive.

On the global stage, Israel and its closest ally appear increasingly isolated. In explaining the US's stance, Ortagus stated that the resolution fails to condemn Hamas or acknowledge Israel's defensive rights and perpetuates misinformation that benefits Hamas.

The international response following the veto has been swift, with representatives from numerous countries expressing their disappointment. Palestinian Ambassador to the UN, Riyad Mansour, called the US's decision deeply regrettable and painful, preventing the Security Council from fulfilling its role in addressing the situation.

As the humanitarian crisis intensifies, with noted casualties in Gaza and rising tensions ahead of the UN General Assembly, the need for a resolution remains urgent. Thousands continue to flee amidst increasing violence from Israeli military actions.
