The United Nations has warned of a "worsening" humanitarian situation in Yemen but said a fragile two-month truce since early April could help reverse the situation.

"The worsening humanitarian crisis in Yemen is a reality that we need to urgently address," UN humanitarian coordinator for Yemen, David Gressly, said in a statement released late Saturday.

"Over 23 million people -- or almost three-quarters of Yemen's population -- now need assistance... an increase of almost three million people from 2021," he said.

An Asiatic cheetah gave birth to three "healthy" cubs in Iran, the head of the environment department said Sunday, calling it a first in captivity for the endangered species.

"Iran", one of only a dozen cheetahs found in the Islamic republic, delivered three "healthy" cubs by C-section, Ali Salajegheh told IRNA news agency.

"This is the first birth of an Asiatic cheetah in captivity," he said.

"By preserving these cubs, we can increase the cheetah population in captivity and then in semi-captivity," Salajegheh added.

Lebanese university students who fled Ukraine are now struggling to complete their education back home, facing a precarious future as an unprecedented economic crisis crushes their country and their career prospects.

"Even war is better than being here," said 25-year-old Yasser Harb, who left Kyiv just two days before Russia invaded Ukraine on February 24.

The final-year medical student is now back in a country where electricity is scarce, public services are dysfunctional at best, the local currency has collapsed and living costs have skyrocketed.

Saudi Arabia is pushing to revamp its harsh justice system but reforms are overshadowed by executions and tough treatment of dissidents, raising questions about how much will change.

The kingdom is known for its strict interpretation of Islamic sharia law, which forms the basis of its judicial system.

But in recent months it has moved ahead with reforms that analysts say could make its courts function more like others in the Middle East.

Three young Israelis formerly serving in military cyber units have figured out how to locate your digital footprint -- and give you the tools to delete it.

The company Mine, co-founded by Gal Ringel, Gal Golan and Kobi Nissan, says it uses artificial intelligence to show users where their information is being stored -- like whether an online shoe store kept your data after a sneaker purchase three years ago.

Saudi Arabia announced that the Muslim holiday of Eid al-Fitr, which marks the end of the holy fasting month of Ramadan, will begin on Monday in the country.

"Monday... is the first day of the blessed Eid al-Fitr for this year," with Sunday the last day of Ramadan, the official Saudi Press Agency said Saturday, citing a royal court statement.

Fellow Gulf states the United Arab Emirates, Kuwait, Qatar and Bahrain have also made the same announcement.

The timing of Eid is determined by the sighting of the crescent moon, in accordance with the Muslim lunar calendar.

The Palestinian Islamist movement Hamas warned Saturday of attacks on synagogues if Israeli forces carry out another raid on the flashpoint Al-Aqsa mosque in annexed east Jerusalem.

"Whoever takes the decision to repeat this scene (of a deployment inside the mosque) will be taking the decision to destroy thousands of synagogues across the world," Yahya Sinwar, Hamas chief in the Gaza Strip, said in a speech.

Dozens of faithful celebrated mass Saturday at a Mosul church in northern Iraq for the first time since it was restored after its ransacking by Islamic State jihadists.

IS swept into Mosul and proclaimed it their "capital" in 2014, in an onslaught that forced hundreds of thousands of Christians in the northern Nineveh province to flee, some to Iraq's nearby Kurdistan region.

The Iraqi army drove out the jihadists three years later after months of gruelling street fighting that devastated the city.

Israeli forces on Saturday arrested the suspected killers of a Jewish settlement guard shot in a West Bank attack claimed by a Palestinian armed group that linked it to violence in Jerusalem.

Al-Aqsa Martyrs' Brigade, one of the main militant groups active in the Israeli-occupied territory, claimed responsibility for the shooting which, along with the killing of a Palestinian, brought a deadly conclusion to a Friday marked by clashes at Jerusalem's flashpoint Al-Aqsa mosque compound.

An end to years of tension between regional rivals Iran and Saudi Arabia is near, Iraqi Prime Minister Mustafa al-Kadhemi said in an interview published on Saturday.

Iraq, a neighbour to both countries, has hosted five rounds of talks over the past year aimed at restoring ties between Sunni Muslim Saudi Arabia, and Shiite-majority Iran.

Following the latest round in Baghdad, Iraqi officials have sounded increasingly optimistic, talking of an imminent sixth session and even going so far as to raise the prospect of a resumption in diplomatic relations severed in 2016.
