Palestinian leader Mahmoud Abbas says he will demand an international resolution that would set a timetable for ending Israeli occupation of Palestinian territories when he speaks to the U.N. General Assembly this week.

If the U.N. rejects his appeal, Abbas says he will seek membership in international institutions and agencies. His aides have said that would include the International Criminal Court.

Joining the court could potentially open the door to war crimes charges against Israel, both for its military actions in Gaza and for ongoing construction of Jewish settlements on occupied lands.

Abbas is set to speak before the General Assembly on Friday. He meets U.S. Secretary of State John Kerry on Tuesday.

Abbas spoke Monday in a lecture at Cooper Union college.
