The Trump administration is letting it be known to Palestinian leaders and the United Nations that it will no longer tolerate anti-Israel actions, The Washington Free Beacon reports.

White House officials and congressional sources told the Free Beacon that President Trump will "unabashedly support Israel" in the months and years ahead.

Their comments came after the administration stunned the U.N. by moving to block the appointment of former Palestinian Prime Minister Salam Fayyad as a special U.N. representative for Libya.

Sources inside the White House told the Free Beacon the move was meant to signal to the Palestinians that this type of action undermines Israel.

"The United States was disappointed to see a letter indicating the intention to appoint the former Palestinian Authority Prime Minister to lead the U.N. Mission in Libya," said Nikki Haley, the U.S. ambassador to the U.N.

"For too long the U.N. has been unfairly biased in favor of the Palestinian Authority to the detriment of our allies in Israel."

"The United States does not currently recognize a Palestinian state or support the signal this appointment would send within the United Nations, however, we encourage the two sides to come together directly on a solution. Going forward the United States will act, not just talk, in support of our allies."

One senior congressional told the Free Beacon that Trump's approach to the U.N. is focused on supporting Israel.

"The U.N. is not a friend of Israel," the source said. "After the Obama administration's eleventh-hour attack on the Jewish state, President Trump is attempting to turn the page.

"Our new administration is already pushing back against the U.N.'s rampant bias and reasserting America's strong support for Israel. This is a good step in the right direction."

CNN reported the U.S. delegation objected to Fayyad's candidacy after first "greenlighting him." The U.S. move effectively blocked his appointment, the news network reported.

"Is this how it is going to work from now on," CNN quoted one unnamed U.N. diplomat. "We have no idea what we can expect."
