The U.S. and some other Western embassies in Kyiv said that they would stay closed Wednesday for security reasons, with the American delegation saying it had received a warning of a potentially significant Russian air attack on the Ukrainian capital.

The precautionary step came after Russian officials promised a response to President Joe Biden's decision to let Ukraine strike targets on Russian soil with U.S.-made missiles — a move that angered the Kremlin.

Four United Nations peacekeepers were wounded in southern Lebanon on Tuesday when a rocket struck a base, while another peacekeeping base was damaged by rocket fire and a patrol was shot at.

In a statement, the peacekeeping mission known as UNIFIL said “a rocket, likely fired by non-state actors within Lebanon,” struck the base of the Ghana's mission in the east of Ramia village, injuring four peacekeepers, three of whom required hospitalization.

The Lebanese Army said an Israeli airstrike targeted one of its military bases late Tuesday in the southern town of Sarafand, killing three Lebanese soldiers. The Health Ministry said at least 17 people were also wounded, including civilians who lived near the facility.

In total, 41 Lebanese soldiers have been killed amid the war between Israel and Hezbollah.

The U.N. peacekeeping chief says diplomatic efforts toward a cease-fire in Lebanon are “encouraging,” and that the United Nations is working on the role its peacekeeping mission in southern Lebanon could play after the Israel-Hezbollah war ends.

Jean-Pierre Lacroix, who just returned from Lebanon and Israel, told reporters Tuesday that the U.N. is proceeding on the basis that Security Council Resolution 1701, which ended the 2006 Israel-Hezbollah war, will remain the framework for a settlement .

Qatar’s foreign ministry spokesperson says Hamas leaders have left Doha but denied reports that Qatar has ordered a permanent closure of the Palestinian militant group’s political office or expulsion of its previously Doha-based leadership.

Qatar, which had served as a mediator in indirect cease-fire negotiations between Israel and Hamas for a cease-fire and hostage exchange deal, has suspended its efforts after growing frustration with the lack of progress on a cease-fire deal for Gaza.

Iraqi Prime Minister Mohammed Shia al-Sudani has dismissed an Israeli complaint to the U.N. Security Council about strikes by Iraq's Iran-backed Shiite militias on Israel as a “pretext and argument to attack Iraq” and to “expand the war in the region.”

Israeli Foreign Minister Gideon Saar had earlier posted on X a letter to the Security Council saying that “Israel has the inherent right to self-defense ... and to take all necessary measures to protect itself and its citizens against the ongoing acts of hostilities by Iranian-backed militias in Iraq.”

The U.N. peacekeeping mission in southern Lebanon, under pressure from an Israeli military campaign against Hezbollah in its area of operations, says Argentina has asked three of its officers in the contingent to return home, while all other contributing countries are maintaining their commitments.

Spokesman Andrea Tenenti of UNIFIL said its “operational capabilities have not changed” after the move by Argentina, and U.N. forces have not moved from their positions -- despite the Israeli army asking them to move from positions near the “blue line” along the Lebanon-Israel border about a month ago.

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."
