Palestinians in the besieged coastal enclave have been staging week-long protests demanding their right to return to the homes and lands their families were expelled from 70 years ago.
It also seeks recommendations from UN Secretary-General Antonio Gutterese on ensuring protection for Palestinian civilians, including an "international protection mechanism".
U.S. ambassador to the United Nations Nikki Haley argued that the original resolution was biased against Israel, and put blame for violence squarely on Israel. The measure, sponsored by Palestine, Turkey and Algeria, comes roughly a month after dozens of Palestinians were killed during protests along the Gaza border. The overwhelming majority of the dead and wounded have been unarmed, according to Gaza health officials.
The U.S. says Israel is unfairly singled out in the draft and has proposed an amendment condemning Hamas for firing rockets into Israel and inciting violence along the Gaza-Israel border fence, "thereby putting civilians at risk". "By their votes, those countries recognized that peace will only be achieved when realities are recognized, including Israel's legitimate security interests, and the need to end Hamas' terrorism", she said. "We want to make sure that doesn't happen", he said.
Turkey´s Ambassador Feridun Hadi Sinirlioglu defended the resolution, saying it was "about taking sides with global law" and showing the Palestinians that the world "does care about their suffering".
Wednesday's assembly meeting reflected the deep divisions that persist over the decades-old Israeli-Palestinian conflict.
Prior to the vote, the U.S. attempted to add an amendment to the bill denouncing Palestinian political and militant group Hamas for its part in stoking violence between Israelis and Palestinians.
His motion to take "no action" on the amendment was defeated by a vote of 59-78 with 26 abstentions, allowing the USA amendment to be put to a vote.
Algerian Ambassador Sabri Boukadoum, representing Arab nations, first sought to block a vote on the USA amendment, saying it wasn't relevant to the resolution. General Assembly President Miroslav Lajcak declared that under United Nations rules a two-thirds vote was needed so the amendment failed.
"We had more countries on the right side than the wrong side", Haley said in a statement.
A USA official also told Axios that the Trump administration wants to launch a peace plan when the circumstances are "right", and that Kushner and Greenblatt are interested in input from the parties involved. The U.S. narrowly lost that vote 66-73 with 26 abstentions.
The resolution passed by a vote of 120-8 with 45 countries abstaining.
