More than 1,000 Palestinians have been killed by Israeli forces since May while trying to get food in the Gaza Strip, mostly near aid sites run by an American contractor, the U.N. human rights office said Tuesday.

Meanwhile, Israeli strikes killed 25 people across Gaza, according to local health officials.

President Donald Trump's special envoy, Steve Witkoff, planned to head to the Middle East as the U.S. tries once again to reach a ceasefire deal between Israel and Hamas, the State Department's spokesperson said Tuesday.

Department spokesperson Tammy Bruce told reporters that Witkoff was going to the region with a "strong hope" that the U.S. can deliver a ceasefire deal as well as a new humanitarian corridor for aid distribution.

Australia's Parliament resumed Tuesday for the first time since the center-left Labor Party won one of the nation's largest-ever majorities in the May elections. The day was largely ceremonial, with reminders of conflict in the Middle East.

Hundreds of pro-Palestinian demonstrators gathered outside Parliament House on Tuesday, calling for the government to impose sanctions on Israel after Australia joined another 27 countries in issuing a joint statement, saying the war in Gaza "must end now."

Yemen's Houthis said they targeted Israel's main airport Tuesday for the second time since Israel struck a rebel-held port a day earlier, with the Israeli army reporting it had intercepted the missile.

The Houthis targeted Ben Gurion International Airport "using a 'Palestine 2' hypersonic ballistic missile", according to military spokesman Yarya Saree, who had hours earlier claimed a similar attack.

The Roman Catholic church's most senior cleric in the Holy Land said Tuesday that the humanitarian situation in Gaza was "morally unacceptable", after visiting the war-torn Palestinian territory.

"We have seen men holding out in the sun for hours in the hope of a simple meal," Latin Patriarch Pierbattista Pizzaballa told a news conference. "It's morally unacceptable and unjustified," he added.

EU foreign policy chief Kaja Kallas said Tuesday she told her Israeli counterpart that Israel's military "must stop" killing civilians at aid distribution points in Gaza.

"The killing of civilians seeking aid in Gaza is indefensible. I spoke again with Gideon Saar to recall our understanding on aid flow and made clear that IDF must stop killing people at distribution points," Kallas wrote on X.

The ceasefire that ended Iran's 12-day war with Israel has held for nearly a month without incident, but many Iranians remain uneasy, struggling with uncertainty as fears of another confrontation linger.

The World Health Organization said its facilities in Gaza had come under Israeli attack, echoing calls from Western countries for an immediate ceasefire as Israel expanded military operations to the central city of Deir el-Balah.

Britain and 24 Western allies, including Australia, Canada, France and Italy, declared on Monday that the war in Gaza "must end now", arguing that civilians' suffering had "reached new depths".

"We urge the parties and the international community to unite in a common effort to bring this terrible conflict to an end, through an immediate, unconditional and permanent ceasefire," the grouping added in a joint statement.
