World powers urged restraint on Sunday for fear that Iran's unprecedented missile and drone strikes on Israel could spark a wider war in the Middle East, as the United Nations heard a call for new sanctions against Tehran.

Iran launched the attack, its first ever to directly target Israeli territory, in retaliation for a deadly air strike widely blamed on Israel that destroyed Tehran's consular building in Syria's capital early this month.

The search for a missing Israeli teenager resumed Saturday in the occupied West Bank, where settler attacks on Palestinian villages have left at least one dead and dozens injured, sources on both sides said.

The Israeli army said it was still looking for Benjamin Achimeir, 14, who went missing early on Friday from Malachi Hashalom, an outpost near the city of Ramallah.

With tensions already high due to the Israel-Hamas war in the other Palestinian territory of Gaza, Israeli security forces and hundreds of volunteers formed a huge search party to look for the teen.

Six months after Hamas's October 7 attack, dozens of hostages are still languishing in captivity -- a fact that for many Israelis has ruptured a foundational contract between them and their government.

"The Jewish people need protection, especially with who we live next to," said Einat Avni Levi, whose family home is within sight of Gaza.

Five of her neighbours in the Nirim kibbutz community were killed and five more taken hostage by Hamas militants on October 7.

The Gaza war is speeding up Israel's "annexation" of the Palestinian economy, say analysts, who argue it has been hobbled for decades by agreements that followed the Oslo peace accords.

While the Israel-Hamas war raging since October 7 has devastated swathes of Gaza, it has also hit the public finances and wider economy of the Israeli-occupied West Bank.

Israel is tightening the noose on the Palestinian Authority, which rules parts of the West Bank, by withholding tax revenues it collects on its behalf, economist Adel Samara told AFP.

Salman Rushdie, targeted for assassination since 1989 over his writing, had long wondered who would kill him. When he was stabbed almost fatally, his first thought was, "So it's you."

The novelist has recounted his thoughts on his 2022 near death in a book, "Knife: Meditations After an Attempted Murder," which is set for publication on Tuesday.

In an excerpt from the book which he read for the CBS News show "60 Minutes," Rushdie described "the last thing my right eye would ever see" -- a man in black clothes "coming in hard and low" like a "squat missile."

An Argentine court has blamed Iran for two deadly attacks on Israeli targets in Buenos Aires three decades ago, declaring it a "terrorist state" in a ruling welcomed Friday by Israeli and Jewish organizations.

The ruling on Thursday, cited by press reports, said Iran had ordered a 1992 attack on the Israeli embassy and another in 1994 on the Argentine Israelite Mutual Association (AMIA) Jewish community center.

Israel launched a massive manhunt in the occupied West Bank Friday after an Israeli teenager went missing, with the search party clashing with Palestinian villagers, sources from both sides said.

Benjamin Achimeir, 14, went missing at around 6:30 am (0330 GMT) from Malachi Hashalom, an outpost near Ramallah, the Israeli army and a family member said.

The Israeli army said that air, ground, police and other forces were involved in the search, "blocking roads and scanning the area".

Iran has vowed to punish Israel over a recent strike on its Damascus consulate widely blamed on Israel, and fears are rising that an imminent response could risk triggering a broader conflict.

However there are a number of different ways that Iran could retaliate, and not all pose the same risk of escalation, according to experts.

With warnings building on Friday that a response could come soon, France advised its citizens not to travel to Israel, the Palestinian territories, Iran or its ally Lebanon.

Thousands of Lebanese on Friday mourned a slain Christian political official authorities said was killed by a Syrian gang, with supporters pointing the finger at Lebanon's powerful Hezbollah group.

Pascal Sleiman was a coordinator in the Byblos (Jbeil) area north of Beirut for the Lebanese Forces (LF) Christian party, which opposes the government in neighbouring Syria and its Lebanese ally Hezbollah.

On Monday, the army said that Sleiman, who had gone missing the day before, was killed in a carjacking by Syrian gang members who then took his body across the border.

Gaza's Tabatibi family is in mourning for the second time in less than a month, after separate Israeli bombardments on buildings they were sheltering in killed more than 60 of their kin.

The latest strike occurred in the early hours of Friday in Gaza City's densely populated Daraj neighbourhood, killing at least 25 members of the family, a relative told AFP.

In a narrow street, the six-storey building where the Tabatibi family had been staying was still standing on Friday, balconies barely hanging to its facade, the ground floor charred and its inside strewn with rubble.
