The display of animous towards the delegation came exactly one week after the Trump administration officially moved the USA embassy in Israel from Tel Aviv to Jerusalem-a move seen as a direct assault on the so-called "peace process" and the demand that East Jerusalem ultimately become the future capital of an independent Palestinian state. The ICC recognizes "Palestine" as a member state. It is vital for the ICC to assume a principled and just stand and open an official, speedy and criminal investigation into Israel's egregious violations being committed throughout occupied Palestine.
"This morning I'm sending out an emergency call to help save Gaza's health system", Commissioner-General of the United Nations Relief and Works Agency for Palestine Refugees (UNRWA) Pierre Krahenbuhl told reporters in Gaza.
Israel has said it was defending its border and accused Gaza's ruling Hamas militant group of using the unrest to carry out attempted attacks and of using civilians as human shields.
Israel is not a member of the ICC however, and the Israeli foreign ministry on Tuesday said it "takes a severe view" of the referral, which it called "a cynical step without legal validity".
It also said the ICC lacks jurisdiction in the case because Israel is not a member of the court.
Speaking at a press conference in Gaza City, Krahenbuhl described the nature of injuries sustained by Palestinian protesters as "shocking".More news: Pompeo's Iran Plan Is a Pipe Dream
The ICC has been conducting a preliminary inquiry since 2015 in the Palestinian territories, including Israel's settlement policy and crimes allegedly committed by both sides in the 2014 Gaza conflict. Amnesty International called the situation in Gaza "another horrific example of the Israeli military using excessive force and live ammunition in a totally deplorable way".
It was a rare show of unity between Shi'a-ruled Iran and Sunni-led Saudi Arabia and other Middle Eastern nations that have been feuding with Tehran over its involvement in the Syrian civil war, support for Huthi rebels in Yemen, and other matters.
"This referral is Palestine's test to the worldwide mechanism of accountability and respect for global law", he added. It says east Jerusalem is an inseparable part of its capital, and considers the West Bank to be disputed territory whose fate should be decided in negotiations.
The Israeli response reflected Israel's strong opposition to the court's potential entanglement in the protracted Israeli-Palestinian dispute and the possibility that Israeli leaders could be indicted - even if by a court they do not recognize.
In late 2016, the UN Security Council also declared the settlements to be illegal.
Under global law it is illegal to transfer populations out of or into occupied territory.
