US special envoy Steve Witkoff and top White House adviser Jared Kushner landed in Israel on Monday and met with Prime Minister Benjamin Netanyahu, just over a week into a shaky ceasefire in Gaza.

The leaders discussed “the developments and updates in the region,” a spokeswoman for the Prime Minister’s Office told journalists, without providing any further details. She added that US Vice President JD Vance and his wife were due to visit Israel “for a few days and will be meeting with the prime minister.”

This week’s visit marks Witkoff and Kushner’s second trip to the country since the Gaza ceasefire deal was signed on October 9. The pair are slated to again visit Hostages Square in Tel Aviv during their trip, as 16 bodies of fallen captives remain held in Gaza.

Their visit is part of a concerted US push to keep the fledgling ceasefire from fraying further, a day after Israel carried out deadly strikes across the Strip in response to an attack by Palestinian gunmen who killed two Israeli soldiers in Rafah, on the Israeli side of the ceasefire line.

Witkoff and Kushner, the architects of the ceasefire-hostage deal, will be joined by Vance on Tuesday, the Israel Airports Authority said in a statement Monday announcing preparations for his arrival at Ben Gurion Airport. Traffic disruptions around the airport are expected between 10:30 a.m. and 1:30 p.m., and some flights are scheduled to be moved to another terminal, the IAA said.

Witkoff and Kushner’s visit and meetings with top Israeli officials will be aimed at further advancing Washington’s Gaza ceasefire framework, a US official told The Times of Israel on Sunday.

Meanwhile, a Hamas delegation was set to meet in Cairo on Monday with officials from ceasefire mediators Qatar and Egypt to discuss the fragile truce, a source close to the talks told AFP.

The source said the delegation, headed by Hamas official Khalil al-Hayya, would discuss “the dozens of airstrikes that killed dozens in the Gaza Strip” on Sunday. Another informed source told AFP on Monday that “mediators’ contacts and efforts succeeded last night in restoring calm and implementing the ceasefire agreement in Gaza.”

The first source told AFP that Hamas’s delegation in Cairo was also set to meet Egyptian officials to discuss an upcoming intra-Palestinian dialogue hosted by Egypt and aiming “to unify the Palestinian factions.”

“The dialogue aims to unify the Palestinian factions and discuss key issues, including the future of the Gaza Strip and the formation of the independent committee of experts that will assume management of the Strip,” the source said.

Under the US-backed ceasefire proposal, an independent transitional authority, run by technocrats, has been proposed to administer Gaza, and several Palestinian political officials recently raised the possibility of a group of unaffiliated Palestinian managers to run the Strip.

Egypt has hosted several such meetings between Palestinian factions, notably including the two main rival political movements, Hamas and Fatah.

The latter, secularist movement, which is led by Palestinian Authority President Mahmoud Abbas, was ousted from Gaza after a brief civil war with Hamas in 2007.

Gaza’s prospective transitional administration would be affiliated with neither Hamas nor the PA, according to the US ceasefire plan. The administration would hand over the reins of Gaza to the PA only once the unpopular body, which Israel accuses of incitement to terrorism in its school system and through payments to terrorists, undergoes significant reforms, according to the plan.

The transitional administration’s precise make-up is among the issues still to be hashed out by negotiators as part of the Gaza ceasefire’s second phase, which would also see Hamas disarm, under the US proposal.

In the meantime, Israel and Hamas have accused each other of violating the ceasefire’s first phase, which saw Israel stage an initial withdrawal inside the Gaza Strip on October 10 and release nearly 2,000 Palestinian prisoners and detainees in exchange for the last 20 living hostages in Gaza.

Israel has accused Hamas of violating the ceasefire’s first phase by both attacking the soldiers in Rafah on Sunday and failing to return bodies of hostages that it has access to. Hamas has denied withholding hostages’ bodies and also denied responsibility for the Sunday attack, saying it was carried out by renegade operatives with whom the terror attack had lost contact.

The White House has appeared to echo Hamas’s claims both regarding the Rafah attack and the bodies of the hostages.

On Sunday, Vance downplayed the renewed violence in Gaza, telling reporters that there would be “fits and starts” in the truce.

“Hamas is going to fire on Israel. Israel is going to have to respond,” he said. “So we think that it has the best chance for a sustainable peace. But even if it does that, it’s going to have hills and valleys, and we’re going to have to monitor the situation.”

Vance also called on Gulf Arab countries to establish a “security infrastructure” in order to ensure that Hamas is disarmed, a key part of the peace deal.

“The Gulf Arab states, our allies, don’t have the security infrastructure in place yet to confirm that Hamas is disarmed,” he said.
