Thousands of worshippers have flocked to a Jewish holy site in northern Israel to light bonfires, pray and dance Wednesday under heavy police presence, a year after a stampede there left 45 people dead.

This year's Lag BaOmer holiday festivities at Mount Meron appeared orderly, but were overshadowed by last year's deaths, the largest civilian disaster in the country's history. A prominent rabbi lit 45 candles in memory of those who perished.

Coming from around the globe, airplanes carrying world leaders have landed in the capital of the United Arab Emirates to offer condolences for the death of the country's president — and acknowledge the influence of the man now fully in charge.

Sheikh Mohammed bin Zayed Al Nahyan rarely speaks publicly. The new president shies away from the United Nations' annual summit in New York. And his thoughts on the world around him come filtered through a tight-knit coterie and leaders who interact with him rather than from his pronouncements.

The world's tallest building disappeared behind a grey layer of dust on Wednesday as sandstorms that have swept the Middle East hit the United Arab Emirates, prompting weather and traffic warnings.

The U.N. special envoy for Iraq warned its political leaders Tuesday that "the streets are about to boil over" because of their deadlock and failure to address a host of issues, including the suffering of ordinary people and armed groups firing rockets with impunity.

Jeannine Hennis-Plasschaert told several reporters after briefing the U.N. Security Council that Iraq and the region cannot afford to go back to October 2019.

A sandstorm engulfed Saudi Arabia's capital and other regions of the desert kingdom Tuesday, hampering visibility and slowing road traffic.

A thick grey haze made iconic Riyadh buildings such as Kingdom Centre nearly impossible to see from more than a few hundred meters (yards) away, though there were no announced flight delays or cancellations. 

For years, the Siyam family clung to hope they would one day be reunited with their son Wassim, who they believed was being held in a Syrian government prison after he went missing at a checkpoint nearly a decade ago.

That hope evaporated the moment they saw him in a newly leaked video: He was among dozens of blindfolded, bound men who, one by one, were shot and thrown into a trench by Syrian security agents.

An attempt by one of Libya's rival prime ministers to seat his government in the capital of Tripoli triggered clashes Tuesday between competing militias, forcing the newly appointed premier to leave the city. The development underscored the fragility of the situation in the war-wracked country.

Prime Minister Fathi Bashagha's office said he had arrived in Tripoli with a number of Cabinet ministers early Tuesday — three months after his appointment to lead an interim government.

As Israel and the Palestinians wrangle over the investigation into the killing of Al Jazeera journalist Shireen Abu Akleh, several independent groups have launched their own probes. One open-source research team said its initial findings lent support to Palestinian witnesses who said she was killed by Israeli fire.

The outcome of these investigations could help shape international opinion over who is responsible for Abu Akleh's death, particularly if an official Israeli military probe drags on. Israel and the Palestinians are locked in a war of narratives that already has put Israel on the defensive.

The first commercial flight in six years took off from Yemen's rebel-held capital on Monday, officials said, part of a fragile truce in the county's grinding civil war.

The flight by national carrier Yemenia — also known as Yemen Airways — was bound for Jordan's capital of Amman, according to media outlets run by the Iran-backed Houthi rebels. It had 151 passengers on board.

The top Catholic clergyman in the Holy Land on Monday condemned the police beating of mourners carrying the casket of Al Jazeera journalist Shireen Abu Akleh, accusing the authorities of violating human rights and disrespecting the Catholic Church.

Latin Patriarch Pierbattista Pizzaballa told reporters at St. Joseph Hospital in Jerusalem that Friday's incident, broadcast around the world, was a "disproportionate use of force" to the Palestinian flag-waving crowd of thousands proceeding from the hospital to a nearby Catholic church in Jerusalem's Old City. The attack drew worldwide condemnation and added to the shock and outrage of Abu Akleh's killing as she covered a shootout in the occupied West Bank.
