A ceasefire between Israel and Hamas held into a third day on Sunday as mediators spoke to all sides about extending the period of calm after the worst outbreak of fighting in years.
Egyptian mediators have been shuttling between Israel and the Gaza Strip, which is ruled by Hamas, to try to sustain the ceasefire and have also met the Islamist group’s rival, Palestinian President Mahmoud Abbas, in the occupied West Bank.
Egypt’s foreign minister was also set to meet with top Jordanian officials to discuss de-escalation and ways to revive the Middle East peace process.
Lynn Hastings, the United Nations Humanitarian Coordinator for the Palestinian territories, said on Sunday the UN would launch an appeal to repair the damage in densely populated Gaza, where there is a threat of COVID-19 spreading.
"The escalation has exacerbated an already dire humanitarian situation in Gaza, generated by nearly 14 years of blockade and internal political divisions, alongside recurrent hostilities," she said in a statement issued from the Palestinian enclave.
"We must also ensure support to continue addressing needs that already existed, including those arising from the ongoing pandemic."
Israel has blockaded Gaza since 2007, saying this prevents Hamas bringing in arms. Hastings said the United Nations had long been asking Israel to stop the blockade and would continue doing so.
US President Joe Biden has said Washington will work with UN agencies on expediting humanitarian aid for Gaza "in a manner that does not permit Hamas to simply restock its military arsenal".
His top diplomat, US Secretary of State Antony Blinken, in television interviews on Sunday said that while the Biden administration was now focused was on aid, reconstruction and diplomacy, an end to violence could help shift gears toward long-term peace.
"We'll be re-engaging with the Palestinians -- of course continuing our deep engagement with the Israelis -- in trying to put in place conditions that allow us over time, hopefully, to advance a genuine peace process. But that is not the immediate order of business," Blinken told CNN's "Fareed Zakaria GPS" program. "We have a lot of work to get to that point."
The United Arab Emirates on Sunday also said it stands ready to facilitate peace efforts.
Palestinian officials put reconstruction costs at tens of millions of dollars in Gaza, where medical officials said 248 people were killed during the 11 days of fighting.
Medics said rocket fire and a guided missile attack killed 13 people in Israel during the hostilities.
Economists said Israel’s recovery from the COVID-19 pandemic could be curbed by the hostilities. Israel reopened its borders to foreign tourists on Sunday but said it would take time to revive the tourism industry.
Israel has fully vaccinated about 55% of its population and COVID-19 cases have dropped sharply.
Israel admitted Jewish visitors on Sunday to a contested Jerusalem holy site where police confrontations with Palestinian protesters helped to ignite the cross-border Gaza fighting on May 10.
Police said this was a regular scheduled visit to the sacred compound known as Temple Mount by Jews and the Noble Sanctuary by Muslims. Israeli social media accounts showed a few dozen Jews in religious garb strolling around the site under guard and police reported no unusual incidents.
The hilltop plateau in Jerusalem's walled Old City is the most sensitive site in the conflict, and was the focus of frequent protests by Palestinians during the Muslim holy month of Ramadan.
The holiest site in Judaism, it is revered by Jews as the site of the Biblical temples of antiquity. It is now dominated by two Muslim shrines, the Dome of the Rock and al-Aqsa Mosque, which is the third-holiest site in Islam.
It is situated in East Jerusalem, which Israel captured and occupied in a 1967 war, later annexing in a move not recognised internationally.
Palestinians seek East Jerusalem, including the Old City, as the capital of a future state. But Israel deems all of Jerusalem to be its capital, citing religious and historical ties.
