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.

Pakistan's interior minister arrived in Iran on Saturday after planned talks between Iran and the United States in Switzerland were postponed, Iranian media reported.

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.

Mediators in the U.S.-Iran conflict, including Pakistan, Saudi Arabia and Turkey, are due to gather for talks in Egypt on Sunday, Cairo and Islamabad said.

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.

President Joseph Aoun on Friday condemned the latest Israeli strikes on eastern and southern Lebanon, saying the "killing and destruction constitutes a dangerous escalation".

"It effectively targets all ongoing efforts to consolidate the ceasefire and end the war," a statement from the presidency said, after Israeli attacks in the south and east killed at least 18 people.

Hezbollah vowed to defend Lebanon's territory and people against Israeli attacks on Friday, accusing its foe of violating a ceasefire as fighting flared.

"The Islamic Resistance will remain vigilant against any aggression. Its fighters will defend their land and people," the Iran-backed group said in a statement, refuting Israeli accusations that it had violated the truce, and instead insisting "the enemy has never complied with any ceasefire agreement".
