Iran on Saturday accused Israel of a strike in Damascus that killed five Revolutionary Guards members, and vowed to avenge the latest attack on the Islamic republic's personnel abroad.

President Ebrahim Raisi said Tehran would not let the "cowardly assassination" go unanswered.

Israel has been accused of intensifying strikes targeting senior Iranian and allied figures in Syria and Lebanon -- backers of the Palestinian militant group Hamas -- raising fears that fighting in the Gaza Strip could spread further.

Iran-backed militants launched ballistic missiles at a base hosting US forces in western Iraq, causing one Iraqi and possible American casualties, the US Central Command said Saturday.

"Multiple ballistic missiles and rockets were launched by Iranian-backed militants in western Iraq targeting al-Assad Airbase," CENTCOM said in a social media post, which placed the time of the attack at 6:30 pm Baghdad time (1530GMT) Saturday evening.

Most of the projectiles were intercepted by the base's air defense systems but "others impacted on the base," the statement said.

Protesters clashed with police in the Italian city of Vicenza on Saturday after a demonstration against the presence of Israeli exhibitors at an international jewellery fair.

Police used water cannon against demonstrators who fired smoke bombs and flares after violence erupted after a planned march by hundreds of people, some holding up banners saying "Free Palestine" and "Stop Bombing Gaza".

More than 1,300 exhibitors from almost 40 countries are showing at the Vicenzaoro fair, which opened on Friday and runs until Tuesday, according to organisers.

Marom sprinted towards a post perched in the mountains above Israel's border with Egypt, slamming her M16 rifle onto a defensive position as part of a training exercise.

The 21-year-old soldier became one of the first Israeli women to fight in a combat role in Gaza, where she recently spent two weeks.

Israel's ground offensive in the Palestinian territory, which came in response to unprecedented attacks by Hamas militants on October 7 against southern Israel, has shifted military attitudes towards women.

An Israeli strike on Damascus killed five people in a building where "Iran-aligned leaders" were meeting on Saturday, a war monitor said, as regional tensions soar over the Israel-Hamas war.

"An Israeli missile strike targeted a four-storey building, killing five people... and destroying the whole building where Iran-aligned leaders were meeting," said the Syrian Observatory for Human Rights.

Fighting raged across Gaza and Israeli units raided the West Bank on Sunday after Prime Minister Benjamin Netanyahu, who has faced growing domestic criticism, rejected calls for post-war "Palestinian sovereignty".

Alongside fierce fighting in southern Gaza and across the besieged territory, strikes in Syria and Iraq raised fears of a wider conflagration.

Hamas-run Gaza's health ministry reported at least 165 people killed over the previous 24 hours -- more than double Friday's toll.

The US military carried out another round of strikes against Yemen's Huthi rebels on Friday, targeting missile launchers that were preparing for attacks on shipping in the Red Sea, the White House said.

Washington is seeking to reduce the Iran-backed Huthis' military capabilities, but the Yemeni rebels are still able to continue their attacks despite a week of strikes, and they have vowed that they will keep targeting merchant vessels.

US President Joe Biden said Friday it was still possible Israeli Prime Minister Benjamin Netanyahu could agree to some form of Palestinian state, after the two leaders spoke for the first time in nearly a month amid tensions over the Gaza war.

Their call came a day after Netanyahu said he opposes allowing Palestinian sovereignty in the wake of the conflict with Hamas, deepening Israeli divisions with key backer Washington over the conduct of Israel's offensive and what comes next.

A top official from Lebanon's Iran-backed militant group Hezbollah on Friday warned Israel would "receive a real slap in the face" if it expanded the conflict along the Lebanon-Israel border.

Since the surprise October 7 attack by Hamas on southern Israel, there have been near daily exchanges of cross-border fire between the Israeli army and Hezbollah, an ally of the Palestinian militants.

Israel has repeatedly bombarded border villages, with the violence killing more than 195 people in Lebanon, including at least 142 Hezbollah fighters, according to an AFP tally.

The SUVs roll to a halt, the pupils run from the room and hop in, the parents speed away -- just like a normal school run, only this was in a bomb shelter.

It's been this way in Jish, an Israeli village with a majority Christian population a stone's throw from the Lebanon border, since the October 7 attack by Hamas on Israel.

Israel's retaliatory strikes and ground invasion of Gaza prompted Lebanese Hezbollah to fire repeatedly at Israel.
