JERUSALEM (AP) -- Palestinians shuttered schools and shops and called for protests in West Bank towns on Thursday, while the leader of the Hamas militant group called for a new armed uprising, in widespread show of anger over President Donald Trump's move to recognize Jerusalem as Israel's capital.
Trump's dramatic break on Wednesday with decades of U.S. policy on Jerusalem counters long-standing international assurances to the Palestinians that the fate of the city will be determined in negotiations. The Palestinians seek Israeli-annexed east Jerusalem, captured by Israel in 1967, as a future capital.
There have been no signs of serious violence so far. But Friday, the Muslim holy day, could provide an important test when Palestinians gather for weekly mass prayers.
In the Gaza Strip, Hamas' leader Ismail Haniyeh called on Palestinians to launch a new intifada, or uprising, against Israel on Friday.
"The American decision is an aggression on our people and a war on our sanctuaries," Haniyeh said in a speech, urging supporters "to be ready for any orders."
"We want the uprising to last and continue to let Trump and the occupation regret this decision," he said.
Hamas, a group that seeks Israel's destruction, killed hundreds of Israelis in suicide bombings and other attacks in the early 2000s. But the group's capabilities are more limited now. Gaza, Hamas' stronghold, is closed by an Israeli blockade, while in the West Bank, many of its members have been arrested. Nonetheless, it possesses a large arsenal of rockets capable of striking much of Israel.
Spontaneous protests sparked in Gaza overnight, with angry youths burning tires, American and Israeli flags and Trump posters.
The Israeli military said it would deploy several battalions to the West Bank ahead of Friday, while other troops have been put on alert to address "possible developments."
The conflicting claims to Jerusalem, and especially its Old City, where sensitive Jewish, Muslim and Christian holy sites are located, lie at the core of the Israeli-Palestinian conflict. While Trump's decision had no impact on the city's daily life, it carried deep symbolic meaning, and was seen as siding with Israel and an attempt to impose a solution on the Palestinians.
Israel, which claims all of Jerusalem as its undivided capital, has welcomed Trump's decision. Prime Minister Benjamin Netanyahu said Trump "bound himself forever" to the history of Jerusalem with the move and claimed other states are considering following suit.
"We are already in contact with other states that will make a similar recognition," he said at the Foreign Ministry on Thursday.
Anger at the U.S. has rippled across the Arab world.
Saudi Arabia's royal court, led by King Salman and his powerful son, condemned the Trump administration's decision in a rare public rebuke by the U.S. ally. The regional powerhouse, which could help the White House push through a Middle East settlement, said Thursday the kingdom had already warned against this step and "continues to express its deep regret at the U.S. administration's decision," describing it "unjustified and irresponsible."
Trump's move puts the Sunni nation in a bind. The kingdom, particularly its powerful crown prince, Mohammad Bin Salman, enjoys close relations with Trump and his son-in-law Jared Kushner, who leads Trump's efforts to restart Mideast peace talks.
U.S. Embassies across much of the Middle East and parts of Africa warned American citizens of possible protests following Trump's move.
Palestinian President Mahmoud Abbas has suggested that with Trump's move, the United States disqualified itself as mediator between Israelis and Palestinians, a role it has played exclusively in more than two decades of stop-and-go negotiations aimed at setting up a Palestinian state alongside Israel.
The talks, stalled in recent years, have failed to bring the Palestinians closer to the state the seek in the West Bank, Gaza Strip and east Jerusalem, lands Israel captured in the 1967 Mideast war. In parallel, Israel has steadily expanded Jewish settlements on war-won lands, even as it said it wants to negotiate a deal.
Trump's claim Wednesday that he still wants to pursue what he has called the "ultimate" Mideast deal was met by mounting skepticism.
"With its decision, the U.S. has isolated itself and Israel, and has pushed the area into a dangerous situation and stopped the peace process," said Nabil Abu Rdeneh, a senior Abbas aid. "Without a doubt, this decision will not help at all in solving the problems in the area, but rather strengthen the extremists."
Abbas has not said what steps he would take, if any. Later Thursday, he was to meet with his closest Arab ally, Jordan's King Abdullah II, to coordinate positions.
Jordan plays a central role in the mounting controversy and, alongside other U.S. allies in the region, has slammed Trump's decision on Jerusalem.
The king is seen as one of Washington's most dependable partners in the battle against Islamic extremism in the region.
At the same time, the legitimacy of his Hashemite dynasty is closely linked to its special role in Jerusalem, as religious guardian of a key Muslim shrine in east Jerusalem. Jordan, which has a large population with Palestinian roots, cannot afford to be seen as soft on Muslim claims to the holy city.
The consultations between the monarch and Abbas will kick off a series of meetings in the Arab and Muslim world on how to respond to Trump.
The Arab League, a group representing most states in the Middle East and North Africa, will meet Saturday. Next week, Turkey will host a gathering of the Organization of Islamic Cooperation, which has 57 Arab and Muslim member states.
The region has been bracing for fallout from Trump's seismic policy shift.
Turkish President Recep Tayyip Erdogan on Thursday accused Trump of throwing the Mideast into a "ring of fire" and said his motives were difficult to fathom. "It's not possible to understand what you are trying to get out of it, Erdogan said, referring to Trump in a speech to a group of workers at Ankara's airport.
"Political leaders exist not to stir things up, but to make peace," Erdogan said. "If Trump says 'I am strong therefore I am right,' he is mistaken."
Defying worldwide warnings, Trump insisted Wednesday that it was time for a new approach, starting with what he said was his decision merely based on reality to recognize Jerusalem as the seat of Israel's government. He also said the U.S. would move its embassy from Tel Aviv to Jerusalem, though he set no timetable.
"We cannot solve our problems by making the same failed assumptions and repeating the same failed strategies of the past," Trump said, brushing aside the appeals for caution from around the world.
