The United Nations Interim Force in Lebanon said Thursday that a peacekeeper was killed and two others wounded when shelling hit their base in the country's south the previous night.

"A UNIFIL peacekeeper died early this morning from critical injuries sustained when mortar shells struck his position," a statement from the force said, adding that an investigation had been launched.

Israel's defense minister said Thursday that a ceasefire agreement with Lebanon grants the military the "freedom" to strike Beirut if Hezbollah attacks Israeli communities, adding that operations in southern Lebanon would continue.

"The IDF will, at this stage, continue its fire and ground operations, remain in the security zone in Lebanon up to the Yellow Line -- including in the Beaufort area -- and without the return of the population, while continuing to dismantle terrorist infrastructure on the ground," Israel Katz said in a statement, as he hailed the ceasefire deal reached on Wednesday.

President Donald Trump said Wednesday he wants to separate talks on the conflict in Lebanon and those on the war between the United States and Iran, although Tehran insists the conflicts are linked.

"I'd like to separate it, I'd like to have a separate thing, because it is, it is separate," Trump told reporters.

An Israeli strike in southern Lebanon killed a paramedic, the state-run National News Agency reported late Wednesday after three other strikes targeted paramedics in south Lebanon in the same day.

The strike on a team from the Hezbollah-affiliated Islamic Health Committee in Zebdine killed a paramedic and wounded another.

Israel's far-right National Security Minister Itamar Ben Gvir criticized on Thursday a ceasefire deal with Lebanon brokered by Washington, calling it a "serious mistake".

"The ceasefire with Lebanon is a serious mistake and the pipe dreams of advisers are dragging the prime minister (Benjamin Netanyahu) to wrong decisions," the minister wrote on X.

Iranian Foreign Minister Abbas Araghchi said Wednesday that lines of communication with the United States were still open, but "no tangible progress" has been made in negotiations to end the Middle East war.

"Communications with the Americans have not been cut off, and messages have been exchanged regarding the need to stop aggression against Beirut, but no tangible progress has been made in the negotiation process," the Tasnim news agency quoted him as telling Lebanon's Al Mayadeen TV.

The fate of Iran's highly enriched uranium stockpiles is at the center of talks with Washington, and Tehran has not yet agreed to a peace deal, U.S. Secretary of State Marco Rubio said Wednesday.

Washington insists that Iran must turn over its near-weapons-grade enriched uranium, agree to curb its nuclear activities and re-open the Strait of Hormuz for any peace agreement to take hold.

Israeli Prime Minister Benjamin Netanyahu said on Wednesday that Iran was "playing with fire" after the Islamic republic carried out an attack on Kuwait.

"Iran surely knows what the (U.S.) president has said, that if necessary, there'll be a full-scale return to military action," Netanyahu said in an interview with U.S. channel CNBC when asked if there was still a ceasefire following recent attacks on Kuwait and Bahrain.

Iranian Foreign Minister Abbas Araghchi warned on Wednesday that any attack on Lebanese capital Beirut would trigger a "full-scale resumption" of the Middle East war, as Israel pressed its campaign against Lebanese militant group Hezbollah.

"Any attack on Beirut will have grave consequences and will lead to a full-scale resumption of the war," the Tasnim news agency quoted Araghchi as telling Lebanon's Al Mayadeen TV. "Our armed forces are ready to strike Israel if it attacks Beirut."

Israeli Prime Minister Benjamin Netanyahu downplayed on Wednesday a row with U.S. President Donald Trump, saying they both were aligned on the goal of disarming Hezbollah in order to achieve peace between Israel and Lebanon.

Trump confirmed in an interview published on Wednesday in the New York Post that he had a tense exchange with Netanyahu two days prior, in which he reportedly berated his close ally with expletives.
