Jordan confirmed it is keen to retain the Hashemite custodianship over the holy sites in Jerusalem and vowed to prevent the Israeli occupation plans to judaize the city, according to the Deputy Speaker of the Lower House, Khamis Attyah.

He made his remarks during the 13th Session of the Parliamentary Union of the OIC members (PUIC) in the Iranian capital,Tehran.

Jordan's custodian role fosters steadfastness of Jerusalem residents and preserves Al-Aqsa Mosque, and urged Arab nations to back this historic Hashemite effort, according to Petra News.

He pointed out that this session was held simultaneous with rigorous challenges triggered by the Mideast volatilities, and noted this tumultuous situation stresses the dire need to bolster dialogue, respect of law, and reciprocal points of view.

Khamis pointed out that Trump’s Jerusalem decision has grave ramifications on the Palestinian cause, the Arab region as well as the world.

It is "a declaration of war on the international law, constitutes the crime of the century, and an infringement of the Palestinian people's rights", he confirmed.

The world's rejection of the US step proved Washington's isolation and plans to thwart this move need a huge pan-Arab effort at international arenas, he pointed out.

The Hashemite custodianship of Jerusalem holy sites refers to the Jordanian royal family role in tending Muslim and Christian holy sites in the city of Jerusalem.

In 2013, King Abdullah II and the Palestinian President, Mahmoud Abbas, signed a historical agreement reaffirming the Jordanian custodianship over Holy Sites in Jerusalem, and the King has the right to exert all legal efforts to safeguard them, especially Al Aqsa Mosque.
