Deputy U.S. Special Envoy for Middle East Morgan Ortagus said that Friday’s ceasefire violation came from Lebanon and that Israel had the right to respond.

She was speaking to Al-Arabiya TV after Israel carried out an airstrike in Beirut’s southern suburbs, the first since the end of the war, in response to two rockets that were fired from Lebanon.

Prime Minister Nawaf Salam on Friday called Israel’s strike on two buildings in the Beirut southern suburb of al-Jamous "a dangerous escalation," urging the army chief "to act quickly to... uncover those behind the irresponsible rocket fire that threatens Lebanon's stability" and arrest them.

Israeli Prime Minister Benjamin Netanyahu said the Israeli airstrike that destroyed two buildings in Dahieh earlier in the day, the first since the latest war with Hezbollah, was “another example” of Israel’s “determination.”

President Joseph Aoun said Friday that he condemns the Israeli airstrike on Beirut’s southern suburbs and any attempt to “bring back the circle of violence” to the country.

Speaking during a news conference in Paris, Aoun said the Lebanese Army is investigating who fired two rockets at north Israel in the morning and “we will not allow anyone to use Lebanon as a launching pad."

The Lebanese Army said Friday it had identified the site of a rocket launch that triggered Israeli strikes, including on Beirut's southern suburbs for the first time since a November Hezbollah-Israel ceasefire.

"The army was able to identify the rocket launch site in the Qaaqaaiyet al-Jisr area" in south Lebanon's Nabatiyeh district just north of the Litani River, an army statement said.

Israeli Defense Minister Israel Katz issued a fresh warning to Lebanon in the wake of an Israeli airstrike on Dahieh earlier in the day.

French President Emmanuel Macron on Friday called an Israeli air strike on a southern suburb of Beirut "unacceptable," saying it was a "violation of the ceasefire" agreed in November.

Such attacks "play into the hands of Hezbollah," Macron told reporters after a meeting with President Joseph Aoun in Paris.

An Israeli airstrike on Friday targeted the Beirut southern suburb of al-Jamous, destroying two buildings, following an Israeli evacuation warning, the first such raid since a November ceasefire largely halted hostilities between Israel and Hezbollah.

TV footage showed heavy black smoke billowing from the area, which is densely populated and home to residential buildings and schools.

The United Nations envoy for Lebanon called for restraint by all sides on Friday, after Israel carried out air strikes in southern Lebanon following new rocket fire towards Israel.

"Today's exchange of fire across the Blue Line, the second such incident in less than a week, is deeply concerning," Jeanine Hennis-Plasschaert said in a statement, four months into a ceasefire between Israel and Hezbollah. "A return to wider conflict in Lebanon would be devastating for civilians on both sides of the Blue Line and must be avoided at all costs. Restraint from all parties is therefore critically needed."

The Israeli army on Friday told residents in a south Beirut suburb to leave the area around "Hezbollah facilities" immediately, the first such warning since a November ceasefire took hold in Lebanon.

"Anyone located in the building marked in red as shown on the map, and the surrounding buildings... are near Hezbollah facilities... you must immediately evacuate these buildings," military spokesman Avichay Adraee said in a post on X that included a map showing the building in the Beirut southern suburb of Saint Therese.
