Yemen's warring parties have agreed to renew a two-month truce, the United Nations said on Thursday, in an 11th-hour move on the day it was set to expire.

Aid agencies and Western governments had urged the Yemeni government and Huthi rebels to extend the truce, which went into effect in April and significantly reduced the intensity of fighting in a conflict the UN says has triggered the world's worst humanitarian crisis.

Israeli troops shot dead a teen in the West Bank on Thursday, the Palestinian health ministry said, the fourth Palestinian killed in the occupied territory in two days.

The ministry identified the slain Palestinian as 17-year-old Odeh Odeh, who was hit in the chest by what it said was an Israeli bullet near the village of Al-Madiya, west of Ramallah.

The Israeli army said "three suspects threw a firebomb" at soldiers "operating near the security barrier" adjacent to Al-Madiya.

Israeli troops killed a Palestinian man during a clash in a refugee camp in the occupied West Bank on Thursday, the Palestinian health ministry said.

The fighting rocked the Dheisheh camp near Bethlehem, a ministry statement said, identifying the dead man as Ayman Muhaisen, 29. Contacted by AFP, the Israeli army had no immediate comment.

The Palestinian death was the third within 24 hours after a woman approaching soldiers with a knife was shot early Wednesday, and a man was killed in an Israeli raid in the northern West Bank later that day.

Adnan Abdelrahman shows off the drums he learned to play at age 12. He belongs to Iraq's centuries-old black minority, guardians of musical traditions but relegated to the margins of society.

Centred in the city of Zubair, near Basra in the far south of Iraq, the community has its origins in East Africa.

Like other remote parts of Iraq, Zubair is a place of poverty and decaying public services, where dusty roads are lined with simple cement houses.

Major oil producers led by Saudi Arabia and Russia hold talks Thursday on whether to adjust output, hard on the heels of an EU ban on Russian oil imports.

Analysts had expected OPEC+ producers to likely stick to their policy of only increasing output modestly, as they have done since May 2021.

However, a Wall Street Journal report on Monday that said OPEC was considering suspending Russia from the output deal has sown doubts.

Iranian government-backed hackers tried to attack a leading US hospital for children in 2020, but were deterred after American authorities learned of the plan, FBI director Chris Wray said Wednesday.

"In the summer of 2020, hackers sponsored by the Iranian government tried to conduct one of the most despicable cyber attacks I've ever seen... when they decided to go after Boston Children's Hospital," Wray said in a speech on cyber threats at Boston College.

Wray said that US authorities received a report from an intelligence partner that the hospital was about to be targeted.

Hundreds of Sudanese protesters on Wednesday demanded the dismissal of the United Nations mission chief, who is working to resolve a political crisis sparked by last year's military coup.

Wednesday's protests, outside the mission's headquarters in the capital Khartoum, criticised efforts by UN special representative Volker Perthes, who heads the United Nations Integrated Transition Assistance Mission Sudan (UNITAMS).

The deadly collapse of a building in southwestern Iran has accentuated anger over price rises and economic deprivation that sparked protests which have now lasted three weeks and show no sign of abating, observers say.

With video footage showing the use of bitter slogans against the government and even supreme leader Ayatollah Ali Khamenei, the protests present a hugely delicate moment for the Islamic republic's leadership.

Turkey's President Recep Tayyip Erdogan on Wednesday renewed threats of a military offensive in northern Syria, which he said would target Kurdish "terrorists".

"We are taking another step in establishing a 30-kilometre security zone along our southern border. We will clean up Tal Rifaat and Manbij", he said, referring to two northern Syrian cities.

Erdogan said they would then proceed, "step by step, into other regions".

For a week now, Turkey's leader has been threatening to launch an operation against fighters of the Kurdistan Workers' Party (PKK).

A fragile UN-brokered truce between the Yemeni government and Huthi rebels hung in the balance Wednesday as talks on renewing it hit trouble, threatening the humanitarian gains of the past two months.

Aid agencies and Western governments have urged Yemen's warring parties to extend the truce, which has significantly reduced the intensity of fighting in a conflict the United Nations says has triggered the world's worst humanitarian crisis.

But with just one day before the truce expires, there was no sign of any breakthrough in UN-backed talks.
