The Palestinians want east Jerusalem as the capital of their future state, and view the relocation of the U.S. embassy from Tel Aviv to Jerusalem as a blatantly one-sided move that invalidates the USA as a peace broker. Mr Trump himself will not be there.
This year's celebration took on added significance due to the embassy move, and the march to the Western Wall included many hardline religious nationalists who oppose a Palestinian state.
Former presidential candidate Michele Bachmann on a visit to Israel has apologized for remarks she made about Jews in the past.
"If and when the Trump peace plan is put on the table, the focal point will be what it says about Jerusalem".
"For 70 years, Jerusalem has been awaiting worldwide recognition, until President Donald Trump, in a courageous move, recognized Jerusalem as the eternal capital of Israel".
Mr Trump has been criticised for handing his ally, Israeli Prime Minister Benjamin Netanyahu, a political victory without insisting on any Israeli concessions that might mollify Palestinians and help revive the moribund peace process.
President Trump is expected to address attendees at Monday's event via video link. The US delegation includes Ivanka Trump, the president's daughter; Jared Kushner, his son-in-law; US Middle East envoy Jason Greenblatt; and a large number of senators and Congressmen.More news: Neymar to resume training on Sunday, says PSG
However, dozens of other foreign diplomats are expected, including representatives from Hungary, Romania and the Czech Republic - countries which reportedly blocked a joint European Union statement on the issue. The world has actively rejected this decision by U.S. President Donald Trump and the state of Israel by overwhelmingly supporting a United Nations resolution protesting Washington's efforts. On Tuesday, Palestinians will mark the Nakba, or "Catastrophe", commemorating over 700,000 Palestinians who fled or were expelled in the 1948 war surrounding the creation of the Israeli state. Adopted as Resolution 181, it also called for a special global regime to separately administer the Holy city of Jerusalem.
Two decades later, another war erupted and Israel captured East Jerusalem and the Old City from Jordan.
This relocation is contentious, because Jerusalem is not legally part of Israel and is considered to be "occupied territory" by the UN. The few foreign embassies built in West Jerusalem moved to the less controversial beachfront city of Tel Aviv.
As to the security situation, "it really doesn't feel any different than being in Jerusalem any other time", the administration official told the Free Beacon.
Flowers decorated as an American flag are seen on a road leading to the US Embassy compound ahead the official opening in Jerusalem, Sunday, May 13, 2018. Palestinians are getting ready for another massive protest Monday near the border with Israel. On Monday, the United States moves its embassy in Israel from Tel Aviv to Jerusalem, the holy city at the explosive core of the Israeli-Palestinian conflict and claimed by both sides as a capital.
A small group of Israelis protested against the march. Rights groups say the use of potentially lethal force against unarmed protesters is unlawful.
