Hezbollah lawmaker Hassan Fadlallah on Saturday said his group had the right to respond to Israeli attacks, as Israel kept up strikes on Lebanon despite a new ceasefire announced a day earlier.

The Lebanese Army said an Israeli strike killed one of its soldiers in the country's south on Saturday, despite a new ceasefire deal between Israel and Hezbollah reached a day earlier.

Hezbollah on Saturday said its fighters confronted overnight Israeli forces as they tried to infiltrate towards strategic hills that overlook the southern city of Nabatieh.

Israel carried out deadly strikes in south Lebanon on Saturday and Hezbollah maintained it had the right to respond, hours after the United States announced a renewed ceasefire in fighting that had strained a fledgling deal with Iran.

The U.S. State Department has announced the resumption of Lebanese-Israeli negotiations in Washington from June 23 to 25.

These discussions will provide an opportunity to "make progress toward a lasting peace," department spokesman Tommy Pigott said in a statement.

President Joseph Aoun told U.S. Secretary of State Marco Rubio in a call Friday that a comprehensive ceasefire must be secured in order for talks with Israel to progress.

The State Department, meanwhile, announced the resumption of negotiations in Washington from June 23 to 25.

Israeli airstrikes and bombardments killed at least 47 people and wounded 97 others in Lebanon on Friday, according to the latest updated toll from the Lebanese health ministry.

The dead included at least seven women and two children and the figures were released as a new ceasefire between Israel and Hezbollah was due to start.

Israel and Hezbollah have agreed a ceasefire that begins 4pm Friday Beirut time, a U.S. official said Friday, after deadly new exchanges in Lebanon put the deal to end the Middle East war under strain.

Iranian Foreign Minister Abbas Araghchi accused Israel on Friday of wanting "permanent war" following remarks from its far-right National Security Minister Itamar Ben Gvir saying "all Lebanon must burn" after four Israeli soldiers were killed there.

"This is not a rant by a random genocidal lunatic. It's a public post by the national security minister of the Israeli regime. The genocidal death cult headquartered in Tel Aviv is a threat to all of humanity. It threatens all humans. Its only interest is permanent war," Araghchi said on X.

The U.S. has "relayed" to Iran that Israel will not further escalate its attacks in Lebanon as the Trump administration seeks to get high-stakes nuclear talks with Iran back on track, a source familiar with the matter told CNN.
