The websites of the Beirut-based, pro-Iranian TV channel Al-Mayadeen have been blocked in Israel over "security" concerns, an official said Monday, as the war in Gaza raises worries of a regional conflict.

At least eight pro-Iran fighters were killed in U.S. strikes on eastern Syria, a war monitor said Monday, after Washington carried out raids a day earlier in response to attacks on American forces.

The toll is "eight pro-Iran fighters dead, including at least one Syrian, and Iraqi nationals", the Syrian Observatory for Human Rights said, following the strikes late Sunday on the Mayadeen and Albu Kamal areas of Syria's eastern Deir Ezzor province near the Iraqi border.

Thousands of people appear to have fled from Gaza's largest hospital as Israeli forces and Palestinian militants battle outside its gates, but hundreds of patients, including dozens of babies at risk of dying because of a lack of electricity, remained inside, health officials said Monday.

With only intermittent communications, it was difficult to reconcile competing claims from the Israeli military, which said it was providing a safe corridor for people to move south, and Palestinian health officials inside the hospital, who said the compound was surrounded by constant heavy gunfire.

Israeli fighter jets carried out strikes against "terror infrastructure" targets inside Syria in response to cross-border fire directed at the Golan Heights, the Israeli military said on Sunday.

"A short while ago, in response to the attack toward the Golan Heights yesterday (Saturday), IDF (Israel Defense Forces) fighter jets struck terror infrastructure sites in Syria," the army said on Telegram.

Israeli strikes pounded Gaza City overnight and into Sunday as ground forces battled Hamas militants near the territory's largest hospital, where health officials say thousands of medics, patients and displaced people are trapped with no electricity and dwindling supplies.

In a televised address on Saturday, Prime Minister Benjamin Netanyahu rejected growing international calls for a cease-fire unless it includes the release of all 239 hostages captured by Hamas in the Oct. 7 attack that triggered the war, saying Israel was bringing its "full force" to the battle.

Iranian President Ebrahim Raisi called Saturday on Islamic governments to designate Israel's military a "terrorist organization," citing its current operations in the Gaza Strip.

Israel's prime minister pushed back Saturday against calls from Western allies to do more to protect Palestinian civilians, as troops bombed and encircled Gaza's largest hospital where doctors said five patients died, including a premature baby, after the last generator ran out of fuel.

Israel has portrayed Shifa Hospital as Hamas' main command post, saying militants were using civilians as human shields there and had set up elaborate bunkers underneath it -- claims Hamas and Shifa staff deny. In recent days, fighting near Shifa and other hospitals in the combat zone of northern Gaza has intensified and supplies have run out.

French President Emmanuel Macron has called on Israel to stop bombing civilians in Gaza, saying there was "no justification" and the deaths were causing "resentment".

In an interview with the BBC, Macron said Israel had the right to protect itself after the October 7 Hamas attacks, but he added: "These babies, these ladies, these old people are bombed and killed.

Arab and Muslim leaders on Saturday condemned Israeli forces' "barbaric" actions in Gaza but declined to approve punitive economic and political steps against Israel over its war against Hamas.

The outcome of a joint summit of the Arab League and the Organization of Islamic Cooperation in the Saudi capital highlighted regional divisions over how to respond to the war even as fears mount that it could draw in other countries.

Israel's prime minister pushed back Saturday against growing calls from Western allies to do more to protect Palestinian civilians, as troops closed in on Gaza's largest hospital that Israel claims is Hamas' main command post but still hosts thousands of patients and people seeking shelter.

Benjamin Netanyahu said the responsibility for any harm to civilians lies with Hamas, repeating long-standing allegations that the militant group uses civilians in Gaza as human shields. He said that while Israel has urged civilians to leave combat zones, "Hamas is doing everything it can to prevent them from leaving."
