Israeli lawmakers on Tuesday unanimously approved a bill to dissolve parliament, a key legislative step that pushes the country closer towards its fifth election in less than four years.

Members of Prime Minister Naftali Bennett's outgoing coalition and the opposition led by ex-premier Benjamin Netanyahu have been sparring in Israel's parliament, the Knesset, since last week over a dissolution bill.

The coalition said it wanted quick approval of the bill after Bennett announced last week that his year-old, ideologically divided, eight-party alliance was no longer tenable.

Iran's chief negotiator joined his US counterpart in Qatar on Tuesday ahead of indirect talks between the two rivals aimed at reviving a landmark nuclear deal, officials and media said.

Ali Bagheri and his delegation arrived in Doha, Iran's IRNA news agency said, after US special envoy Robert Malley held talks with Qatar's Deputy Prime Minister and Foreign Minister Mohammed bin Abdulrahman Al Thani.

Thirteen people were killed, including at least four Asian migrants, when toxic chlorine gas escaped on the dockside in the Jordanian Red Sea port of Aqaba, officials said.

More than 250 people were injured in the accident Monday, of whom 123 remained in hospital on Tuesday, according to the latest toll update.

Most were being treated for the effects of breathing chlorine gas, a common cleaning agent that also has a range of other industrial uses and can be employed as a chemical weapons agent.

A US drone strike in northwestern Syria killed a Yemeni leader of a local jihadist group affiliated to Al-Qaeda, the US military and a Syrian war monitor said.

The strike, carried out on Monday just before midnight (2100 GMT) on the eastern edge of the city of Idlib, took out a man described as a leader of the Hurras al-Deen group.

"Abu Hamzah al Yemeni was travelling alone on a motorcycle at the time of the strike," US Central Command said in a statement, adding that an "initial review indicates no civilian casualties".

A chlorine gas explosion killed 12 people and injured more than 250 on Monday, authorities said, when a tank that fell from a crane released a poisonous yellow cloud at Jordan's Aqaba port.

Footage on state-owned Al-Mamlaka TV showed the large cylinder, said to have been carrying about 30 tonnes of gas, plunging from a crane on a moored vessel and violently releasing the chlorine gas cloud.

The force of the blast sent a truck rolling down the dock, while port workers ran for their lives.

Ten people were killed and more than 200 injured Monday in a toxic gas explosion in Jordan's Aqaba port, authorities said.

Footage on state TV showed a large cylinder plunging from a crane on a moored vessel, causing a violent release of a yellow gas.

The force of the blast sent a truck rolling down the harbourside, while port workers could be seen running for their lives.

Nearby areas were evacuated and residents told to stay indoors.

The death toll rose to 10, government spokesman Faisal al-Shaboul told AFP, revising an initial toll of five killed.

Israeli authorities on Monday dedicated a new museum near Tel Aviv to a magnificent Roman-era mosaic returning to its original home after years of touring the world's top museums.

The mosaic, with vibrant colours that have survived the passage of time, measures around 17 by nine metres (55 by 30 feet), depicting roaring lions, elephants in battle, giraffes and dolphins, as well as fruits, flowers in baskets, and sailing vessels.

Iran and the United States plan to resume indirect talks this week in Qatar, in a fresh bid to revive the landmark 2015 nuclear deal, both sides said Monday.

The talks will be separate from broader EU-mediated negotiations in Vienna between Iran and major powers, the bloc's top diplomat Josep Borrell said Saturday in Tehran.

The nuclear deal has been hanging by a thread since 2018, when then US president Donald Trump unilaterally withdrew from it and began reimposing harsh economic sanctions on America's arch enemy.

Iran announced Monday that weavers in the southern province of Fars had produced the world's largest kilim rug, measuring an enormous 105 square metres (more than 1,100 square feet).

The 7x15-metre kilim was the handiwork of seven expert weavers and three assistants in the town of Qirokarzin, said Mohammad-Jafar Ebrahimi, the local cultural heritage chief, as quoted on state television.

He said it was commissioned by the energy-rich Gulf state of Qatar.

Trust among the Greek- and Turkish-Cypriot communities on their divided island is at a low point but their cooperation in combatting last week's wildfire was "very positive", a senior UN diplomat said Monday.

UN chief of mission Colin Stewart met Cyprus President Nicos Anastasiades, the Greek-Cypriot leader, days after his community helped the Turkish Cypriots battle a huge blaze in Kantara in the northern mountain range.

"I thanked him for the support of the Greek Cypriots for the terrible fire that had been raging in the north over a few days last week," Stewart said.
