Palestinian health authorities and United Nations agencies on Sunday began a large-scale campaign of vaccinations against polio in the Gaza Strip, hoping to prevent an outbreak in the territory that has been ravaged by the ongoing Israel-Hamas war.

Authorities plan to vaccinate children in central Gaza until Wednesday before moving on to the more devastated northern and southern parts of the strip. The campaign began with a small number of vaccinations on Saturday and aims to reach about 640,000 children.

Israel on Sunday said it had recovered the bodies of six captives in Gaza, including a young Israeli-American man who became one of the most well-known captives held by Hamas as his parents met with world leaders and pressed for his release, including at the Democratic convention last month.

The Israeli military said Friday it had wrapped up a month-long operation in southern and central Gaza that it said killed more than 250 Palestinian fighters.

An Egyptian worker was killed Friday in a hotel fight that wounded three Arab-Israeli tourists and other workers in the Egyptian seaside town of Taba, a medical source told AFP.

The worker succumbed to his injuries "in an ambulance transporting him from Taba" on the border with Israel to Sharm al-Sheikh, 200 kilometers south, the source said, requesting anonymity because they were not authorized to speak to the media.

Two Palestinians were killed and three Israeli soldiers were wounded in two attempted car bombings and related clashes overnight in the occupied West Bank.

The Israeli army said the two Palestinians were killed while preparing to carry out bombings in the West Bank, where an Israeli operation entered a fourth day.

The UK on Friday said it was deeply concerned by the Israeli military's ongoing operation in the occupied West Bank, urging it to "exercise restraint" and "adhere to international law".

"We recognize Israel's need to defend itself against security threats, but we are deeply worried by the methods Israel has employed and by reports of civilian casualties and the destruction of civilian infrastructure," a Foreign Office spokesperson said.

An Israeli missile hit a convoy carrying medical supplies and fuel to an Emirati hospital in the Gaza Strip, killing several people from a local transportation company, the American Near East Refugee Aid group said Friday. Israel claimed without immediate evidence that it opened fire after gunmen seized the convoy.

The strike killed several people employed by a transportation company that the aid group was using to bring supplies to the Emirates Red Crescent Hospital in Rafah, said Sandra Rasheed, Anera's director for the Palestinian territories.

It was their most challenging mission.

U.S. Army soldiers in the 7th Transportation Brigade had previously set up a pier during training and in exercises overseas but never had dealt with the wild combination of turbulent weather, security threats and sweeping personnel restrictions that surrounded the Gaza humanitarian aid project.

Israel is carrying out large-scale military raids in parts of the occupied West Bank, where the decadeslong conflict with the Palestinians had worsened even before the outbreak of the war in Gaza.

Israel says the operation, which appeared to be the largest since the start of the war, is aimed at preventing attacks on its citizens. Palestinians view such raids as part of an effort to cement Israeli control over the territory, where 3 million Palestinians live under military rule.

Yemen's Houthi rebels have released footage showing their fighters boarded and placed explosives on a Greek-flagged tanker, setting off blasts that put the Red Sea at risk of a major oil spill. The vessel was abandoned earlier, after the Houthis repeatedly attacked it.

In the video, the Iran-backed Houthis chant their motto as the bombs detonated aboard the oil tanker Sounion: "God is the greatest; death to America; death to Israel; curse the Jews; victory to Islam."
