WASHINGTON (AP) -- President Donald Trump will host Israeli Prime Minister Benjamin Netanyahu for talks at the White House next Monday as the U.S. leader steps up his push on the Israeli government and Hamas to broker a ceasefire and hostage agreement and bring about an end to the war in Gaza.

The impending visit was confirmed by two U.S. administration officials who spoke on the condition of anonymity because they were not authorized to comment publicly on it.

The trip will be Netanyahu's third visit to the White House since Trump returned to office in January, and it comes after the United States inserted itself into Israel's war against Iran by attacking Iranian nuclear sites. After brokering a ceasefire between the two countries, Trump has signaled that he's turning his attention to bringing a close to the fighting between Israel and Hamas.

Trump on Friday told reporters that "we think within the next week we're going to get a ceasefire" in Gaza, but didn't offer any further explanation for his optimism.

White House press secretary Karoline Leavitt said Monday that Trump and administration officials were in constant communication with Israeli leadership and that bringing about an end to the Gaza conflict is a priority for Trump.

"It's heartbreaking to see the images that have come out from both Israel and Gaza throughout this war, and the president wants to see it end," Leavitt added. "He wants to save lives."

Israeli Minister for Strategic Affairs Ron Dermer is in Washington this week for talks with senior administration officials on a Gaza ceasefire, Iran and other matters.

Talks between Israel and Hamas have repeatedly faltered over a major sticking point -- whether the war should end as part of any ceasefire agreement. About 50 hostages remain captive in Gaza, with less than half believed to be alive.

With Netanyahu's visit, the timing of which was first reported by Axios, Trump will embrace the Israeli leader while continuing to push back against skeptical questions from Democratic lawmakers and others about how far U.S. and Israeli strikes have set back Iran's nuclear program.

A preliminary report issued by the U.S. Defense Intelligence Agency, meanwhile, said the strikes did significant damage to the Fordo, Natanz and Isfahan sites, but did not totally destroy the facilities.

Rafael Grossi, head of the International Atomic Energy Agency, said on CBS' "Face the Nation" on Sunday that the three Iranian sites with "capabilities in terms of treatment, conversion and enrichment of uranium have been destroyed to an important degree." But, he added, "some is still standing," and that because capabilities remain, "if they so wish, they will be able to start doing this again." He said assessing the full damage comes down to Iran allowing inspectors access.

Trump in recent days has also inserted himself into Israeli domestic affairs, calling for charges against Netanyahu in his ongoing corruption trial to be thrown out. He has condemned the trial as a "WITCH HUNT" and vowed that the United States will be the one who "saves" Netanyahu from serious corruption charges.

The decision by Trump to plunge himself into one of Israel's most heated debates has unnerved some in its political class.

Meanwhile, the Trump administration on Monday approved a new half-billion-dollar arms sale to Israel to resupply its military with bomb guidance kits for precision munitions.

The State Department said the sale is worth $510 million. It includes more than 7,000 guidance kits for two different types of Joint Direct Attack Munitions, or JDAMs.

The deal is relatively small given that the U.S. provides Israel with more than $3 billion annually in military aid. But Israel has relied on JDAMs and other related US weaponry in its war against Hamas in Gaza and its recent strikes against Iran.

"The United States is committed to the security of Israel, and it is vital to U.S. national interests to assist Israel to develop and maintain a strong and ready self-defense capability," the department said in a statement. "This proposed sale is consistent with those objectives."
