East Jerusalem
In the Palestine Liberation Organization (PLO)'s Palestinian Declaration of Independence of 1988, Jerusalem is stated to be the capital of the State of Palestine. In 2000, the Palestinian Authority passed a law proclaiming Jerusalem as its capital, and in October 2002, this law was approved by chairman Yasser Arafat. Since that time Israel has shut down all offices and NGO organisations connected to the PLO in East Jerusalem, saying that the Oslo Accords do not permit the Palestinian National Authority to operate in Jerusalem. The Organisation of Islamic Cooperation (OIC) recognised East Jerusalem as capital of the State of Palestine on 13 December 2017.

He has said that there are two possible solutions to the Israeli–Palestinian conflict: "an independent Palestinian state" covering, at the very least, all the area within the 1967 frontiers, and with its capital in East Jerusalem, and with all settlements dismantled, or "a single democratic state," no longer exclusively Jewish, "in which all citizens are equal." He complains that Israel "has sought to trap the Palestinians into a corner of the chessboard where there's no longer any choice. If we agree on a two-state solution, we are offered bantustans. And if we say that in those conditions, we'd prefer a single, bi-national state, then we are accused of wanting to destroy Israel."
