GAZA/CAIRO (Reuters) -Weakened by hunger, many Gazans trek across a ruined landscape each day to haul all their drinking and washing water - a painful load that is still far below the levels needed to keep people healthy.

Even as global attention has turned to starvation in Gaza, where after 22 months of a devastating Israeli military campaign a global hunger monitor says a famine scenario is unfolding, the water crisis is just as severe according to aid groups.

(Reuters) -U.S. President Donald Trump will host the leaders of Armenia and Azerbaijan for peace talks at the White House on Friday, a U.S. official told Reuters.

The official said it was possible that the framework for a peace agreement could be announced at Friday's meeting. The Washington Post was first to report on the talks.

(Reuters) -Russia lodged a formal protest to Israel following an alleged attack on a Russian diplomatic vehicle near the settlement of Givat Assaf near Jerusalem, according to a statement issued by the Russian foreign ministry.

WASHINGTON (Reuters) -U.S. President Donald Trump declined to say whether he supported or opposed a potential military takeover of Gaza by Israel and said his administration's focus was on increasing food access to the Palestinian enclave under assault from Washington's ally.

"As far as the rest of it, I really can't say. That's going to be pretty much up to Israel," Trump told reporters on Tuesday.

Israeli Prime Minister Benjamin Netanyahu met senior security officials on Tuesday, with media reporting he favored a complete military takeover of Gaza.

(Reuters) -The United Nations on Tuesday called reports about a possible decision to expand Israel's military operations throughout the Gaza Strip "deeply alarming" if true.

U.N. Assistant Secretary-General Miroslav Jenca told a U.N. Security Council meeting on the situation in Gaza that such a move "would risk catastrophic consequences ... and could further endanger the lives of the remaining hostages in Gaza.

"International law is clear in the regard; Gaza is and must remain an integral part of the future Palestinian state," he added.

BERLIN (Reuters) -More than 100 Israeli academics have warned in a letter that a failure by Germany to put pressure on Israel could lead to new atrocities in Gaza.

"Further hesitation on Germany's part threatens to enable new atrocities - and undermines the lessons learnt from its own history," the academics wrote in the letter, addressed to senior Social Democrat (SPD) lawmakers Rolf Muetzenich and Adis Ahmetovic and seen by Reuters on Tuesday.

More countries must recognise a Palestinian state and stand up to Israel to stop its "genocidal activities", South Africa's Foreign Minister Ronald Lamola told AFP in an interview Tuesday.

Pretoria has been a leading critic of Israel's actions in Gaza, bringing a case before the UN's top court in December 2023 arguing that its war in the Palestinian territory amounted to genocide.

As some of Israel's allies "are now also saying, no, this can't continue, it means that it is bringing us closer and closer to the Israel regime (stopping) the genocidal activities", Lamola said.

The brother of Israeli hostage Evyatar David called on the world to "come together" to secure his freedom following the publication of a video in which the emaciated captive was shown purportedly digging his own grave.

David, 24, is one of 251 people taken captive by Hamas and its allies during their October 7, 2023 attack on southern Israel, which triggered the war in Gaza.

More than 90 people were killed when a migrant boat sank off Yemen's coast, Yemeni officials and a source at the International Organization for Migration told AFP Tuesday, updating earlier tolls.

The boat carrying mostly Ethiopian migrants sank on Sunday as it headed towards Abyan governorate in southern Yemen, a frequent destination for boats smuggling African migrants hoping to reach the wealthy Gulf states.

BEIRUT (Reuters) -Hezbollah chief Naim Qassem threatened Israel directly for the first time in months in a televised speech on Tuesday, saying missiles would fall on it if it resumed a broad war on Lebanon.

His comments came as Lebanon's cabinet met to discuss the fate of Hezbollah's arsenal, after Washington pressured Lebanese officials to commit to disarming the Iran-backed group and amid fears that Israel could intensify strikes if they fail to do so.
