Palestinian Authority (PA) President Mahmoud Abbas said Wednesday that the Palestinians are withdrawing from all peace agreements with Israel since the 1993 Oslo Accords.

Abbas’s comments came during a special meeting of the 57-member Organisation of Islamic Cooperation (OIC) in Istanbul that was convened in response to U.S. recognition of Jerusalem as Israel’s capital.

The PA president said he would refuse any future U.S. involvement in the peace process and threatened that there will be “no peace or stability” in the region until Jerusalem is recognized as the Palestinian capital.

“We will tell the Israelis that we are no longer committed to any agreement from Oslo until today,” he said, adding that the PA would push for full membership in the United Nations, where the Palestinians currently have non-member observer state status.

“We agreed with America we would not join international institutions on the condition that American does not transfer its embassy, does not initiate any action against our office in Washington and orders Israel to freeze settlement building,” Abbas said.
