In a jarring contrast, Israeli forces shot and killed at least 55 Palestinians and wounded more than 1,200 during mass protests along the Gaza border, while just a few miles away Israel and the US held a festive inauguration ceremony for the new American Embassy in contested Jerusalem.
Monday was by far the deadliest day of cross-border violence since a devastating 2014 war between Israel and Gaza's Hamas rulers, and further dimmed the already bleak prospects for President Donald Trump's hoped-for peace plan.
Throughout the day, Gaza protesters set tires ablaze, sending thick plumes of black smoke into the air, and hurled firebombs and stones toward Israeli troops across the border.
The Israeli military, which has come under international criticism for using excessive force against unarmed protesters, said Hamas tried to carry out bombing and shooting attacks under the cover of the protests and released video of protesters ripping away parts of the barbed-wire border fence.
Yesterday's protests culminated more than a month of weekly demonstrations aimed at breaking a crippling Israeli-Egyptian border blockade. But the U.S. Embassy move, bitterly opposed by the Palestinians, added further fuel.
There was barely any mention of the Gaza violence at Monday's lavish inauguration ceremony for the new embassy, an upgraded consular building located just 50 miles (80 kilometers) away. Israeli Prime Minister Benjamin Netanyahu and other top officials joined an American delegation of Trump administration officials and Republican and evangelical Christian supporters.
Jared Kushner, Trump's son-in-law and chief Mideast adviser, headlined the US delegation with his wife and fellow White House adviser, Ivanka Trump, as well as Treasury Secretary Steven Mnuchin and four Republican senators. Republican super-donor Sheldon Adelson was also present, and evangelical pastors Robert Jeffress and John Hagee delivered blessings.
"A great day for Israel!" Trump tweeted earlier Monday.
In a videotaped address, Trump said the embassy move, a key campaign promise, recognizes the "plain reality" that Jerusalem is Israel's capital. Yet he added the United States "remains fully committed to facilitating a lasting peace agreement."
But yesterday's steadily climbing death toll and wall-to-wall condemnation of the embassy move in the Arab world raised new doubts about Trump's ambitions to broker what he called the "deal of the century." More than a year after taking office, Trump's Mideast team has yet to produce a long-promised peace plan.
Trump says recognizing Jerusalem as Israel's capital acknowledges the reality that Israel's government is located there as well as the ancient Jewish connection to the city. He insists the decision has no impact on future negotiations on the city's final borders.
But to both Israel and the Palestinians, the American gesture is widely seen as siding with Israel on the most sensitive issue in their longstanding conflict. "What a glorious day. Remember this moment. This is history," Netanyahu told the inauguration ceremony.
"You can only build peace on truth, and the truth is that Jerusalem has been and will always be the capital of the Jewish people, the capital of the Jewish state," he added. The Palestinians, who seek east Jerusalem as their capital, have cut off ties with the Trump administration and say the U.S. is unfit to serve as a mediator. Israel captured east Jerusalem in the 1967 Mideast war and annexed the area in a move that is not internationally recognized.
Palestinian President Mahmoud Abbas, furious over the embassy ceremony, said he "will not accept" any peace deal proposed by the Trump administration. The Palestinian president also urged the international community to condemn what he said were "massacres" carried out by Israeli troops in Gaza, and officials said the Palestinians would file a war crimes complaint against Israel in the International Criminal Court over settlement construction.
By nightfall, at least 55 Palestinians, including a young girl and four other minors, were killed, the Gaza Health Ministry said. It said 1,204 Palestinians were wounded by gunfire, including 116 who were in serious or critical condition.
Egypt, an important Israeli ally, condemned the killings of Palestinian protesters, while the UN human rights chief, Zeid Ra'ad al-Hussein, decried the "shocking killing of dozens." Turkey said it was recalling its ambassador to the United States over the U.S. Embassy move, saying it "disregarded the legitimate rights of the Palestinian people" and would "not serve peace, security and stability in the region."
It also recalled its ambassador to Israel following what it called a "massacre" of Palestinians on the Gaza border.
South Africa, a fervent supporter of the Palestinians, also recalled its ambassador for consultations, the Israeli Foreign Ministry said.
The European Union's foreign policy chief, Federica Mogherini, called on Israel to respect the "principle of proportionality in the use of force" and show restraint, while also urging Hamas to ensure any protests remain peaceful. U.N. Secretary-General Antonio Guterres issued a similar appeal.
