These actions include settlement, confiscation of Palestinian land, demolition of homes, the displacement of Palestinians from their homes and the ongoing Israeli incursions into Palestinian cities, according to the Egyptian Presidency Spokesman.
The three leaders called on the International community to protect the Palestinian people and their legitimate rights.
They urged all relevant parties to intensify the efforts to relaunch peace negotiations between the Israelis and palestenians to resolve the Palestinian issue based on the two-state solution.
Sisi, Abu Mazen and King Abdullah II agreed on the necessity to safeguard legitimate Palestinian rights and to establish an independent Palestinian state on 4 June 1967 borders, with East Jerusalem as its capital, in line with international laws, related United Nations Security Council resolutions and the Arab Peace Initiative.
They warned of the continuing absence of a political solution to the Palestinian issue and the repercussions such absence has on security and stability.
The constant violations of the historical and legal status quo in Jerusalem and its holy sites were among the main issues discussed in the summit meeting in Cairo.
The three leaders stressed the need to preserve the historical and legal status quo in Jerusalem and its Islamic and Christian holy sites in a way that guarantees the designation of the blessed Al-Aqsa Mosque, Al-Haram Al-Sharif, and its entire area of 144 dunums (144,000 square metres) as an exclusively Muslim place of worship. The Jordanian Ministry of Endowment and Islamic affairs and Holy Places must also be designated as the only place that manages the Mosque’s affairs and regulates access to it.
Earlier on Tuesday, the Jordanian Foreign Ministry summoned the Israeli ambassador to Amman to protest a move by the Israeli police to block the Jordanian ambassador to Israel, Ghassan Majali, from entering the Al-Aqsa Mosque compound earlier.
This is the second time Jordan has summoned the Israeli ambassador to Amman since Prime Minister Benjamin Netanyahu's new right-wing and religiously conservative government took power.
Earlier this month, Israel's minister of national security, the ultranationalist Itamar Ben-Gvir, violated international law by entering the Jerusalem holy site; a move which angered the Palestinians and set off a cascade of condemnations from across the Arab world.
Abdullah and Abu Mazen also praised Egyptian efforts to keep the truce in the Gaza strip and to continue its reconstruction. They also praised Egypt's affirmation of the responsibility of international donors towards reconstruction efforts in Gaza as well as the support Egypt provides for the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) in aiding palestinian refugees.
According to the Egyptian Presidency, both El-Sisi and Abu Mazen reaffirmed the importance of the historical Hashemite sole custodianship over Islamic and Christian holy sites in Jerusalem and its role in protecting these holy sites and their Arab, Islamic and Christian identity.
They also stressed the importance of unifying Palestinian factions and ending any division that might undermine their efforts in defending their cause.
