TEHRAN (Iran News) –Iranian President Ebrahim Raisi has called America “the most important supporter of the killing of women and children in Gaza.”

President Raisi, in a tweet on Sunday evening, reacted to the U.S. veto of the UAE-drafted resolution which called for an immediate ceasefire in the Gaza Strip.

“While the world demands an end to Zionist war crimes in Palestine, the U.S.’s veto of the UNSC ceasefire resolution proves it is the root of this war & crimes, and it’s fueling Israel’s mass killing machine. It is the main supporter of the massacre of innocent Gazan women & children,” the statement read.

The United States vetoed the resolution backed by almost all other Council members. The U.S. move took place as the UN chief called the situation in Gaza a “humanitarian nightmare.”

Thirteen Security Council members voted in favor of a brief draft resolution, put forward by the United Arab Emirates, while the United Kingdom abstained.

The vote came after UN Secretary-General Antonio Guterres made a rare move on Wednesday to formally warn the 15-member Council of a threat to global peace and security from the two-month-long war in the Gaza Strip.

In the wake of the U.S. administration’s stance regarding the ceasefire in the Gaza Strip, Robert Wood, deputy U.S. ambassador to the UN, said, “We do not support calls for an immediate ceasefire. This would only plant the seeds for the next war.”

The U.S. veto once more proved Washington is an accomplice to Tel Aviv’s war crimes, genocide, and war against humanity in the Gaza Strip.

It is the second time since the beginning of the Gaza war that the U.S. has vetoed a resolution, aligning itself with Israel. The U.S. claims a ceasefire would help Hamas to rearm and keep hold of its 138 hostages in the Strip.

On Oct. 18, a day after the bombardment of Al-Ahli hospital in northern Gaza by the Israeli army, the U.S. alone also blocked a similar resolution calling for a ceasefire presented by Brazil. It argued that the text did not mention “Israel’s right to self-defense.”
