JERUSALEM (AP) — U.S. Secretary of State Antony Blinken vowed Tuesday to “rally international support” to aid Gaza following a devastating war there while keeping any assistance out of the hands of its militant Hamas rulers, as he began a regional tour to shore up last week’s cease-fire.

The 11-day war between Israel and Hamas killed more than 250 people, mostly Palestinians, and caused widespread destruction in the impoverished coastal territory. The truce that came into effect Friday has so far held, but it did not address any of the underlying issues in the Israeli-Palestinian conflict, something Blinken acknowledged after meeting with Israeli Prime Minister Benjamin Netanyahu.

“We know that to prevent a return to violence, we have to use the space created to address a larger set of underlying issues and challenges. And that begins with tackling the grave humanitarian situation in Gaza and starting to rebuild,” he said.

“The United States will work to rally international support around that effort while also making our own significant contributions.” He added that the U.S. would work with its partners “to ensure that Hamas does not benefit from the reconstruction assistance."

Blinken will not be meeting with Hamas, which does not recognize Israel’s right to exist and which Israel and the U.S. consider a terrorist organization.

Blinken addressed the larger conflict, saying "we believe that Palestinians and Israelis equally deserve to live safely and securely, to enjoy equal measures of freedom, opportunity and democracy, to be treated with dignity.”

But the top U.S. diplomat faces the same obstacles that have stifled a wider peace process for more than a decade, including a hawkish Israeli leadership, Palestinian divisions and deeply rooted tensions surrounding Jerusalem and its holy sites. The Biden administration had initially hoped to avoid being drawn into the intractable conflict and focus on other foreign policy priorities before the violence broke out.

Netanyahu, meanwhile, is fighting for his political life after a fourth inconclusive election in two years. He faces mounting criticism from Israelis who say he ended the offensive prematurely, without forcibly halting rocket attacks or dealing a heavier blow to Hamas.

Netanyahu hardly mentioned the Palestinians in his remarks, in which he warned of a “very powerful" response if Hamas breaks the cease-fire.

Netanyahu spoke of “building economic growth” in the occupied West Bank, but said there will be no peace until the Palestinians recognize Israel as a “Jewish state.” The Palestinians have long objected to that language, saying it undermines the rights of Israel’s own Palestinian minority.

The war was triggered by weeks of clashes in Jerusalem between Israeli police and Palestinian protesters in and around the Al-Aqsa Mosque compound, a site revered by Jews and Muslims that has seen several outbreaks of Israeli-Palestinian violence over the years. The protests were directed at Israel’s policing of the area during the Muslim holy month of Ramadan and the threatened eviction of dozens of Palestinian families by Jewish settlers.

The truce remains tenuous since tensions are still high in Jerusalem and the fate of the Palestinian families is not yet resolved.

The evictions were put on hold just before the Gaza fighting erupted, but the legal process is set to resume in the coming weeks. Police briefly clashed with protesters at Al-Aqsa on Friday, hours after the cease-fire came into effect.

Adding to the tensions, an Israeli soldier and a civilian were stabbed and wounded in east Jerusalem on Monday before police shot and killed the assailant in what they described as a terrorist attack.

Then, early Tuesday, a Palestinian man was shot and killed by undercover Israeli forces near the West Bank city of Ramallah, according to the Wafa news agency. Pictures circulating online appeared to show the man bloodied and lying in the street. The Israeli army referred questions to the Border Police, which did not respond to requests for comment.

Blinken will head to Ramallah later Tuesday to meet with Palestinian President Mahmoud Abbas, who has no power in Gaza and was sidelined by recent events. Abbas heads the internationally backed Palestinian Authority, which administers parts of the occupied West Bank but whose forces were driven from Gaza when Hamas seized power there in 2007.

Abbas, who called off the first Palestinian elections in 15 years last month when it appeared his fractured Fatah movement would suffer an embarrassing defeat, is seen by many Palestinians as having lost all legitimacy. A crowd of worshippers at Al-Aqsa chanted against the Palestinian Authority and in support of Hamas on Friday.

But Abbas is still seen internationally as the representative of the Palestinian people and a key partner in the long-defunct peace process. The Palestine Liberation Organization, the umbrella group led by Abbas, recognized Israel decades ago, and the Palestinian Authority maintains close security ties with Israel.

Blinken will also visit neighboring Egypt and Jordan, which have acted as mediators in the conflict. Egypt succeeded in brokering the Gaza truce after the Biden administration pressed Israel to wind down its offensive.

The administration had been roundly criticized for its perceived hands-off initial response to the deadly violence, including from Democratic allies in Congress who demanded it take a tougher line on Israel. Biden repeatedly affirmed what he said was Israel’s right to defend itself from rocket attacks from Gaza.

The administration has defended its response by saying it engaged in intense, but quiet, high-level diplomacy to support a cease-fire.

Blinken has said the time is not right for an immediate resumption in Israeli-Palestinian negotiations, but that steps could be taken to repair the damage from Israeli airstrikes, which destroyed hundreds of homes and damaged infrastructure in Gaza.

The narrow coastal territory, home to more than 2 million Palestinians, has been under a crippling Israeli-Egyptian blockade since Hamas seized power. Israel says the blockade is needed to keep Hamas from importing arms, while the Palestinians and human rights groups view it as a form of collective punishment.
