Palestinians have aborted U.S. attempts to exclude Palestine from the Organization for the Prohibition of Chemical Weapons (OPCW), the foreign minister said Saturday.

Riyad al-Malki said the Palestinian delegation to the OPCW’s Fourth Review Conference has rejected “U.S. attempts to add an article in the final document to cast doubts on the membership of Palestine” in the watchdog.

“Most member states have defended Palestine’s right to equal representation with other states,” he added in a statement.

Palestine officially joined the world’s chemical weapons watchdog in June.

The top Palestinian diplomat went on to vow to pursue efforts to bring Israel to accountability for using chemical weapons against the Palestinians.

OPCW member nations have failed to agree on a final document at the conference, which was held in The Hague on November 21-30.

The OPCW, an international chemical weapons watchdog, has been servicing as the implementing body for the Chemical Weapons Convention since its entry into force in 1997.
