Jimmy Carter's critics turned his name into a synonym for weakness over the Iranian hostage crisis. But by any measure, he also scored major achievements on the world stage through his mix of moralism and painstaking personal diplomacy.

The 39th president of the United States, who died at age 100 on Sunday, transformed the Middle East by brokering the Camp David Accords, which established an enduring and once inconceivable peace between Israel and its most serious adversary at the time, Egypt.

Syria's new leader Ahmed al-Sharaa told Al Arabiya TV on Sunday that elections could take four years, noted the importance of ties with Iran and Russia, and called for the United States to lift sanctions.

In a wide-ranging interview three weeks after his Islamist group Hayat Tahrir al-Sham and allied rebels ousted longtime ruler Bashar al-Assad from power after a lightning offensive, Sharaa also said that local Kurdish-led forces which Turkey opposes should be integrated into the national army.

"The election process could take four years," Sharaa told Saudi-owned Al Arabiya.

Gaza's civil defence agency said an air strike hit a hospital Sunday, killing at least seven people, while Israel said it had targeted militants at the no longer functioning facility.

"Seven martyrs and several injured people, including critical cases, have been recovered following the Israeli strike on the upper floor of Al-Wafaa Hospital in central Gaza City," a civil defence agency statement said.

Israel's military said on Saturday it had ended its raid on "a Hamas command centre" in a north Gaza hospital and detained its director as a suspected Hamas operative.

Since October 6, Israeli operations in the Palestinian territory have concentrated on the north, where they are carrying out a land and air offensive they say aims to prevent Hamas militants from regrouping.

As part of its offensive, the military launched a raid early Friday on northern Gaza's Kamal Adwan Hospital, which had been one of the area's two remaining functional medical facilities.

Layan Al Nasr, 14, thought she would never walk again after both of her legs were amputated following an Israeli bombing in Gaza one year ago.

Now, she stands proudly on artificial limbs fitted in the United Arab Emirates. But fear for her family, still living under the attacks, gnaws away.

"When I was told about prosthetics when I arrived, I didn't even know they existed," she jokes, taking a few steps supported by crutches.

She is able to smile as she describes her operations, rehabilitation and her newfound hope. But emotion eventually catches up with her.

A senior official from Libya's UN-recognised government met Syria's new leader Ahmed al-Sharaa in Damascus on Saturday and discussed issues including diplomatic relations, energy and migration.

"We expressed our full support for the Syrian authorities in the success of the important transitional phase," Libyan Minister of State for Communication and Political Affairs Walid Ellafi told reporters after the meeting.

The head of the World Health Organization said Saturday he only narrowly escaped death in fatal Israeli strikes on the airport in Yemen's Huthi rebel-held capital.

WHO chief Tedros Adhanom Ghebreyesus told BBC radio his ears were still ringing following Thursday's attack as he prepared to board a flight in Sanaa, and stressed that the protection for civilian installations under international law must be respected.

A delegation from Turkey's main pro-Kurdish DEM party is due on Saturday to visit jailed PKK leader Abdullah Ocalan, who is serving life on a prison island off Istanbul, a party source said.

"The delegation left in the morning," the source told AFP, without elaborating how they would travel to the island for security reasons.

The visit would be the party's first in almost 10 years.

DEM's predecessor, the HDP party, last met Ocalan in April 2015.

Israel's military on Saturday said a hospital director is being held as a suspected Hamas militant after a north Gaza raid the World Health Organization said left the area's last major health facility emptied of patients and staff.

The military said the director of Kamal Adwan Hospital, Hossam Abu Safiyeh, is being held for questioning, on suspicion of "being a Hamas terrorist operative", and that the raid is now over.

Gaza health officials and the WHO earlier Saturday said the raid forced the hospital in Beit Lahia out of service and led to Abu Safiyeh's detention.

The top UN official for humanitarian aid in Yemen, who narrowly dodged an aerial bombing raid by Israel on Sanaa's airport, denied Friday that the facility had any military purpose.

Israel said that it was targeting "military infrastructure" in Thursday's raids and that targets around the country were used by Huthis to "smuggle Iranian weapons" and bring in senior Iranian officials.

UN humanitarian coordinator Julien Harneis said the airport "is a civilian location that is used by the United Nations."
