Israel's military issued evacuation warnings on Saturday for residents of 13 villages in southern Lebanon and pushed deeper into the country, even as military delegations from Beirut and Tel Aviv held landmark security talks in Washington .
The delegations held talks at the Pentagon and ahead of US-brokered negotiations early next week - the fourth round since the latest Israel-Hezbollah conflict erupted.
Israel has kept up its heavy bombardment of southern Lebanon, with President Joseph Aoun emphasising in a call with US Secretary of State Marco Rubio "the need to exert all efforts to reach a ceasefire".
A truce to halt the fighting between Israel and Iran-backed Hezbollah officially took effect on 17 April, but has never been observed, and Iran insists that Lebanon be included in any agreement with the United States to end the wider war that engulfed the region in February.
Both Israel and Hezbollah accuse each other of violating the ceasefire and justify their attacks by the other's alleged breaches.
The Israeli military's evacuation warnings for Saturday included some villages near Nabatiyeh in the heart of south Lebanon.
Also on Saturday, Hezbollah said it fired rockets at the northern Israeli town of Kiryat Shmona.
The group later said it ambushed Israeli soldiers near the village of Ghandouriyeh, saying it forced them to withdraw, and fired rockets at a military base in north Israel.
On Friday, Hezbollah had said it launched attacks in northern Israel and Israel's military confirmed intercepting several projectiles from Lebanon, with one hitting near Kiryat Shmona.
Hezbollah also said it attacked Israeli troops trying to advance near the medieval Beaufort fortress , also known as Qalaat al-Chqeef, which Israel's forces had used as a base during their two-decade occupation of southern Lebanon that ended in 2000.
Netanyahu announced Friday that Israeli forces had advanced beyond the Litani River that runs around 30 kilometres (20 miles) north of the Lebanon-Israel frontier.
"Our forces have crossed the Litani, they have moved up to the commanding terrain," he said, adding Israel was "hitting Hezbollah head on". Wave of displacement Israel and Lebanon began direct talks in April, with a fourth round expected next week in Washington following Friday's meeting at the Pentagon, running parallel to US efforts to strike a deal with Iran to end the regional war.
Elbridge Colby, the Pentagon's second-in-command, called the discussions "productive" in a post on X.
Israeli strikes in the southern city of Tyre killed 11 people on Friday, according to Lebanon's health ministry, which called the bombardment a "flagrant violation of humanitarian law".
Lebanon was drawn deeper into the regional war when Hezbollah launched rockets at Israel in early March in retaliation for the death of Iran's supreme leader in US-Israeli strikes. Israel had already been violating a 2024 ceasefire with near-daily attacks on Lebanon.
Hezbollah strongly opposes the talks with Israel and has refused to disarm.
On Friday, Lebanon's state-run National News Agency (NNA) reported Israeli airstrikes on more than 20 locations in the south.
Hundreds of people have fled to the usually touristic old city of Tyre, which has not been included in recent Israeli army evacuation orders issued for the rest of the city and surrounding areas.
With shelters full, displaced residents were sleeping in cars or tents, an AFP correspondent said.
"The situation is very difficult. Tyre is a peaceful, touristic city. We never imagined going through this," said Karam Amin, 43, whose family of seven have been sleeping in his clothing shop.
Lebanon's health ministry said on Friday Israeli attacks have killed at least 3,355 people since 2 March 2 - an increase of 31 compared to Thursday when Israeli carried out its first airstrike near Beirut in weeks.
