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.
Thawabit
Al-Thawabit al-Wataniyya (), shortened as Thawabit ('fundamental principles') and sometimes referred to as Palestinian red-lines, are a set of supra-constitutional principles that were formulated by the Palestinian National Council of the Palestinian Liberation Organization (PLO) in 1977, representing the core issues of national consensus on the Israeli–Palestinian conflict and to which all Palestinian factions must pledge fealty: including the right to resistance, the right to self-determination (statehood), Jerusalem as the capital of Palestine, and the right of Palestinian refugees to return (in accordance with UNGA 194).
