A U.S. envoy has arrived in Beirut to meet with Lebanese officials about a possible cease-fire in the Israel-Hezbollah war.

Amos Hochstein, a senior advisor to United States President Joe Biden, arrived Tuesday, a day after Hezbollah reportedly gave a positive response to a U.S. draft proposal to end the war, which has been ongoing for more than 13 months.

An Israeli airstrike targeted the main water facility in the southern port city of Tyre, killing two local officials and injuring two others, further compounding southern Lebanon’s worsening water crisis, Lebanon’s state media said.

The attack severely damaged the facility, prompting the Tyre Municipality to urge residents to ration water use until repairs can be made, the National News Agency said.

Israeli Prime Minister Benjamin Netanyahu said Monday that Israel's late October attack on Iran damaged "a component" of the Islamic Republic's nuclear program.

"It has been published that a certain component of their nuclear program was hit in this attack", Netanyahu told the Israeli parliament, adding that "the program itself and its ability to operate here have not yet been thwarted."

The Lebanese government has largely endorsed U.S. truce proposal to end the Israel-Hezbollah war and was preparing final comments before sending a response to Washington, a Lebanese official told AFP on Monday.

Since September 23, Israel has intensified its air campaign in Lebanon, later sending in ground troops, nearly a year into limited exchanges of fire initiated by Hezbollah in support of Palestinian ally Hamas after its October 7, 2023 attack sparked the Gaza war.

Minutes after an Israeli strike killed at least four in central Beirut, caretaker Prime Minister Najib Mikati said in a post on X, “All countries and decision-makers are required to end the bloody and destructive Israeli aggression on Lebanon and implement international resolutions, most notably Resolution 1701.”

U.N. Security Council Resolution 1701, adopted in 2006, was intended to create a buffer zone in southern Lebanon and end hostilities between Israel and Hezbollah. However, the resolution’s full implementation has faced challenges from both sides.

The European Union on Monday widened sanctions against Iran over its support for Russia's war on Ukraine, including targeting vessels and ports used to transfer drones and missiles.

The 27-nation bloc agreed to prohibit any transaction with ports "used for the transfer of Iranian UAVs or missiles or related technology and components to Russia," said a statement issued as EU foreign ministers met in Brussels.

A Russian ballistic missile with cluster munitions struck a residential area of a northern Ukraine city, killing 11 people including two children and injuring 84 others, officials said Monday.

The two children killed in the strike on Sumy late Sunday were a 9-year-old boy and a 14-year-old girl, the regional prosecutor's office said. Six injured children are in critical condition, it said.

A suspected attack by Yemen's Houthi rebels targeted a commercial ship late Sunday night traveling through the southern reaches of the Red Sea, though it caused no damage nor injuries, authorities said.

The attack comes as the rebels continue their monthslong assault targeting shipping through a waterway that typically sees $1 trillion in goods pass through it a year over the Israel-Hamas war in Gaza and Israel's ground offensive in Lebanon.

An Israeli airstrike hit a computer shop in central Beirut's Mar Elias area on Sunday evening, killing two people and wounding 13, the Health Ministry said.

Al-Arabiya television identified the target of the strike as "Hezbollah military commander Mahmoud Madi," saying the computer shop is owned by his brother.

Hezbollah spokesman Mohammad Afif was killed Sunday in a rare Israeli airstrike targeting the center of the capital Beirut -- outside Hezbollah's traditional strongholds of Dahieh, the south and the Bekaa, a Hezbollah official said.

The strike -- in the Ras al-Nabaa area near Sodeco Square -- targeted a building containing the headquarters of the Lebanese branch of the Baath Party that rules Syria. A Baath member who survived the strike said the building also contained an apartment housing displaced Lebanese.
