The United States has vetoed a resolution at the UN Security Council calling for a ceasefire and unrestricted humanitarian access in Gaza, which Washington said undermined ongoing diplomacy, AFP reports.

It was the 15-member body’s first vote on the situation since November, when the United States — a key Israeli ally — also blocked a text calling for an end to fighting.

“Today, the United States sent a strong message by vetoing a counterproductive UN Security Council resolution on Gaza targeting Israel,” Secretary of State Marco Rubio said in a statement after Wednesday’s 14 to 1 vote.

He said Washington would not support any text that “draws a false equivalence between Israel and Hamas, or disregards Israel’s right to defend itself”. “The United States will continue to stand with Israel at the UN.”

The draft resolution had demanded “an immediate, unconditional and permanent ceasefire in Gaza respected by all parties”.

It also called for the “immediate, dignified and unconditional release of all hostages held by Hamas and other groups”, and demanded the lifting of all restrictions on the entry of humanitarian aid into Gaza.
