The Palestinians have suspended contacts with the CIA after announcing the end to security coordination with Israel and the United States in protest at Israeli proposals to annex territory in the West Bank, a Palestinian official said on Thursday. 

Palestinian President Mahmoud Abbas on Tuesday declared an end to all agreements and understandings with Israel and the United States, at an emergency meeting, according to Palestinian news agency Wafa. 

Washington had been told of the move, Saeb Erekat, secretary-general of the Palestine Liberation Organization, said after Abbas' declare. 

On cooperation with the U.S. Central Intelligence Agency (CIA), Erekat told reporters in a video call: "It stopped as of the end of the (Palestinian) president's speech."

Intelligence cooperation with the CIA continued even after the Palestinians began boycotting U.S. peace efforts led by President Donald Trump in 2017, with the sides working together on heading off violence in the Israeli-occupied West Bank, where the Palestinian Authority is based. 

Speaking after a meeting of the Palestinian leadership in Ramallah, the 85-year-old leader said Israeli annexation of any parts of the occupied West Bank would ruin chances for a two-state solution.

Abbas has made multiple previous threats to end security cooperation with Israel without ultimately following through. He did not give any details about what his latest declaration would mean in practice. 

But Erekat said:" Things change and we have decided it is time now to change."

"Security cooperation with the United States is no more. Security coordination with Israel is no more," said Erekat. "We are going to maintain public order and the rule of law, alone." 

The U.S. embassy in Jerusalem declined to comment. 

Later in the day, a senior Palestinian security official told reporters that Palestinian forces had begun to pull back from some areas of the West Bank that they had policed in coordination with Israel during the coronavirus crisis. 

"In light of the president's instructions about ceasing security coordination, the Israeli side was notified" of the partial withdrawal. 

Israeli officials had no immediate comment and it was not clear how widespread the Palestinian forces' drawback was. 

Palestinians worry that Israel, with Washington's blessing, could carry out pledges to apply Israeli sovereignty to Jewish settlements and the Jordan Valley in the West Bank, which they see as annexation. 

Palestinians seek statehood in the West Bank and Gaza, with East Jerusalem as their capital.

The United States, as a "primary partner with the Israeli occupation government," will be "fully responsible for the oppression of the Palestinian people," Abbas said.
