Five killed in Lebanon as Israeli forces advance across key Litani River 

At least five people have been killed in Israeli air strikes targeting towns in southern Lebanon, as Lebanese and Israeli military delegations plan to hold security talks at the Pentagon.

The attacks on Friday came as Prime Minister Benjamin Netanyahu said Israeli forces had crossed the Litani River in Lebanon, which runs about 30 kilometres north of their shared border, in an expanded ground offensive.

Israel’s latest military operation started despite the “ceasefire” that began on April 17, and was extended for 45 days on May 17 following indirect talks mediated by the United States.

Israel-Lebanon talks

At the Pentagon talks later on Friday, Lebanon will demand that Israel halt its ongoing attacks, which have intensified in recent days.

The Lebanese delegation includes six officers, headed by the army’s director of operations, Georges Rizkallah.

On the Israeli side, Brigadier General Amichai Levin, head of the strategic division within the army’s planning directorate, is in Washington for the talks, according to an Israeli military spokesman.

Lebanese President Joseph Aoun told US Secretary of State Marco Rubio that a ceasefire with Israel was crucial. A statement from his office said that during a phone call, Aoun “emphasised the need to exert all efforts to reach a ceasefire, considering it an essential gateway to moving on to any other step”.

Rubio reiterated the US administration’s commitment to consolidating the outcomes of previous ambassador-level negotiations between Israel and Lebanon in Washington, and expressed his support for Lebanon’s stability, independence and sovereignty, the statement added.

‘Eleven children killed, injured every 24 hours’

In Friday’s attacks on southern Lebanon, four people were killed in an Israeli strike on a building in the town of Abbasiyeh, near the city of Tyre. Another person was killed in a separate strike on Deir Qanoun al-Nahr, Lebanon’s National News Agency (NNA) reported.

NNA said Israeli forces also carried out a new series of air raids on the towns of al-Baisariyah, as-Sarafand and Khirbet Selm. Also targeted was a motorcycle on a road near al-Abbassieh causing injuries.

Fifteen children have been killed in Lebanon and 62 injured over the last seven days, the United Nations said.

The UN children’s agency, UNICEF, called the figures “staggering”, and stressed that, under international humanitarian law, children have to be protected at all times during conflict.

“According to the Lebanese Ministry of Public Health, 77 children have reportedly been killed or injured over the past week alone,” UNICEF spokesman Ricardo Pires told a media briefing in Geneva.

“Fifteen children killed and 62 injured in seven days. That’s an average of 11 children every 24 hours. We understand the vast majority of these children were impacted by air strikes in south Lebanon. Only yesterday, seven children were killed and 30 injured,” he added.

A humanitarian catastrophe

Several aid organisations fear they may have to pull out of southern Lebanon because of relentless attacks.

Hundreds of thousands of Lebanese have been forced from their homes by Israel’s military since March 2, and require urgent humanitarian assistance.

“If the security situation continues to deteriorate, we might have to leave certain areas. There are certain red lines we cannot cross for the security of our teams,” Jeremy Ristord, with medical NGO Doctors Without Borders, known by its French initials MSF, told Al Jazeera.

About 40 hospitals in the south are already closed, he noted.

“On top of that, rescue teams are already working under intense strain in adapting their interventions in the face of the degrading security situation,” said Ristord, noting that rescuers fear “double-tap strikes” by Israel.

“Sometimes they’re not even able to intervene.”

He noted that 126 civil defence workers have been killed and 310 wounded in the war since March – “that’s four casualties a day”.

Israeli military ‘heavily bombarding’ Hezbollah

Also on Friday, the Israeli military issued evacuation warnings for an additional seven towns in southern Lebanon, two of them about 40 kilometres (25 miles) north of Israel.

The Israeli prime minister visited troops near the border, according to a video released by his office.

There, he said ⁠that Israeli forces ⁠had crossed Lebanon’s Litani River and advanced; and that ⁠they were ⁠also operating in Beirut and the ⁠Bekaa Valley as ⁠part ⁠of actions against Hezbollah across the Lebanese ‌front.

“Netanyahu made a surprise visit to the Lebanese border on Friday, confirming that Israeli troops are now positioned north of the Litani River; there has been a focus of Israeli firepower … throughout Nabatieh district,” said Al Jazeera’s Obaida Hitto, reporting from Tyre in Lebanon.

Israeli troops have broken through Hezbollah’s second lines of defence, and are now “heavily bombarding” the armed group’s third lines of defence”, Hitto added.
