Iran's acting foreign minister dismissed a Gaza cease-fire deal proposed by U.S. President Joe Biden and warned Israel against launching an all-out war on Lebanon during a visit to Beirut Monday, his first official diplomatic visit since his predecessor died last month.

Ali Bagheri Kani replaced Hossein Amirabdollahian, a hard-liner close to the paramilitary Revolutionary Guard, who died in a helicopter crash on May 19 in a mountainous area near Iran's border with Azerbaijan, along with Iranian President Ebrahim Raisi and a delegation of other officials.

Palestinian health officials said Israeli strikes killed 11 people overnight into Monday, including a woman and three children, in central Gaza.

A strike on a home in the built-up Bureij refugee camp late Sunday killed four people, including the three children. The second strike, early Monday, killed seven people, including a woman, in the Nuseirat refugee camp.

Throughout its grinding seven-month war with Hamas, Israel has pledged to investigate a series of deadly events in which its military forces are suspected of wrongdoing. The commitment comes in the face of mounting claims — from human rights groups and the International Criminal Court 's chief prosecutor — that the country's leaders are committing war crimes in Hamas-ruled Gaza.

In one of the highest-profile cases, an attack on a World Central Kitchen convoy that killed six foreign aid workers and their Palestinian driver, the Israeli army promptly published its findings, acknowledged misconduct by its forces and dismissed two soldiers. But other investigations remain open, and admissions of guilt are rare.

Patients lying shackled and blindfolded on more than a dozen beds inside a white tent in the desert. Surgeries performed without adequate painkillers. Doctors who remain anonymous.

These are some of the conditions at Israel's only hospital dedicated to treating Palestinians detained by the military in the Gaza Strip, three people who have worked there told The Associated Press, confirming similar accounts from human rights groups.

At the base of the sacred Western Wall in Jerusalem's Old City, President Javier Milei of Argentina appeared to be in a spiritual trance.

With head and hands pressed against the ancient stone, he prayed with the Orthodox rabbi who introduced him to Judaism three years ago. Although born and raised Roman Catholic, Milei has increasingly shown public interest in Judaism and even expressed intentions to convert.

Doubts were growing on Monday about a plan for a Gaza ceasefire and hostage release deal outlined by U.S. President Joe Biden as heavy fighting raged for a third day since his White House address.

Biden on Friday presented what he labelled an Israeli three-phase plan that would end the bloody conflict, free all hostages and lead to the reconstruction of the devastated Palestinian territory without Hamas in power.

At least 12 pro-regime fighters were killed in an overnight Israeli strike that targeted a factory near Aleppo in the north of Syria, an NGO reported early Monday.

"Twelve pro-Iranian fighters of Syrian and foreign nationalities were killed, according to an initial tally, in an Israeli air strike on a position in the town of Hayyan, north of Aleppo, setting off strong explosions in a factory," the Syrian Observatory for Human Rights said.

Israel's prime minister faced growing pressure Saturday after U.S. President Joe Biden announced a proposed agreement to end the fighting in Gaza, with many Israelis urging Benjamin Netanyahu to embrace the deal but far-right allies threatening to collapse his government if he does.

Netanyahu called a permanent cease-fire in Gaza a "nonstarter" until long-standing conditions for ending the war are met, appearing to undermine the proposal that Biden described as an Israeli one.

Qatari, Egyptian and U.S. mediators have called on Israel and Hamas to "finalise" the truce deal outlined by US President Joe Biden, as Israeli forces pounded Rafah in southern Gaza.

Fighting has raged in the besieged Gaza Strip since Biden said Israel was offering a new roadmap towards a full ceasefire.

Congressional leaders have invited Israeli Prime Minister Benjamin Netanyahu to deliver an address a the Capitol, a show of wartime support for the longtime ally despite mounting political divisions over Israel's military assault on Gaza.

The invitation from House Speaker Mike Johnson, a Republican, and Senate Majority Leader Chuck Schumer, a Democrat, along with Senate Republican leader Mitch McConnell and House Democratic leader Hakeem Jeffries, has been in the works for some time. No date for the speech was set.
