Israel has pressed on with its campaigns in Lebanon and Gaza, launching several deadly strikes as Prime Minister Benjamin Netanyahu visited his country's northern border.
The latest attacks on eastern Lebanon came after Israel warned it would again hit Hezbollah targets there.
A town near the southern city of Sidon was also hit.
"I want to be clear: with or without an agreement, the key to restoring peace and security in the north...is first and foremost to push Hezbollah back beyond the Litani River, secondly to target any attempt to rearm, and thirdly to respond firmly to any action taken against us," Mr Netanyahu told troops at the border, according to a statement from his office.
His visit came as Israel's military said more than 100 projectiles were fired from Lebanon into Israeli territory today.
Several were intercepted, and some fell in unpopulated areas.

Israel and Iran-backed Hezbollah in Lebanon have been at war since 23 September, when Israel escalated cross-border air raids after a year of tit-for-tat exchanges of fire.
A week later it sent in ground troops on "targeted raids".
Hezbollah said it was acting in support of Palestinian militants Hamas, whose unprecedented attack against Israel on 7 October last year triggered the ongoing war in Gaza.
"The Israeli enemy's raid on Haret Saida resulted in an initial death toll of three people killed and nine others injured," Lebanon's health ministry said, referring to a densely populated area near Sidon.
Lebanon's official National News Agency (NNA) reported another Israeli strike south of Sidon, on the town of Ghaziyeh, while an AFP correspondent said a child was rescued from the rubble of a residential building.
NNA said other Israeli strikes hit near a hospital in Tebnine, a town in the south Lebanon district of Bint Jbeil.
The health ministry said the hospital sustained "severe damage", adding that seven people were wounded in the attack.
Neither the Haret Saida strike nor those in Lebanon's south were preceded by an Israeli warning to evacuate.
Israel's military did issue a warning for Lebanon's Baalbek area, saying it would be attacking Hezbollah-linked facilities.
An AFP correspondent later reported at least three strikes in the Baalbek area, where Hezbollah holds sway and which has seen heavy air raids over the past few days.
Earlier, Lebanese state media reported the recovery of five bodies from the flashpoint southern town of Khiam.
They were among 21 bodies that have been trapped under rubble there for around a week, according to the NNA.
Hezbollah published an undated video of an underground facility dubbed "Imad 5", showing a hatch opening and a missile pointing skywards.
In the footage, fighters are also seen moving through an apparently underground tunnel carved into the rock.
The war has killed more than 1,940 people in Lebanon since 23 September, according to an AFP tally of Lebanese health ministry figures.
Israel's military says 38 soldiers have been killed in the Lebanon campaign since it began ground operations.
Iran and Israel have recently attacked each other directly, heightening fears of even wider conflict.
However, Iran's President Masoud Pezeshkian said a potential ceasefire with its allies Hamas and Hezbollah "could affect the intensity and type of our response".
The Islamic republic's supreme leader Ayatollah Ali Khamenei had warned Israel and the United States they "will definitely receive a tooth-breaking response".
Israel has warned Iran against responding to its 26 October attack.
American B-52 bombers have arrived in the Middle East, the US military said, as part of reinforcements being deployed as a warning to Iran.
In Gaza, Israel's military again reported "dozens" of militants killed in the northern Jabalia area where Israeli forces have since 6 October carried out a major air and ground assault to stop Hamas from regrouping.
Gaza rescuers and medics said Israeli strikes in Gaza killed at least 30 people across the territory, including in Beit Lahia and Jabalia in the north.
In central Gaza, people crowded to receive sacks of flour from a distribution point of the United Nations agency for Palestinian refugees (UNRWA) in Deir el-Balah.
Israel's parliament last Monday banned UNRWA, the main aid agency in Gaza, from operating in Israel and occupied east Jerusalem, despite international objections.
If implemented, the ban would hit humanitarian work in Gaza, experts say.
The ban came after the United States on 15 October warned Israel it could withhold some of its billions of dollars in military assistance unless it improves aid delivery to Gaza within 30 days.
Also in Deir el-Balah, relatives at Al-Aqsa Martyrs Hospital mourned a father and son killed during Israeli bombardment.
At least 43,341 people in Gaza, a majority of them civilians, have been killed since 7 October last year, according to figures from the territory's health ministry which the United Nations consider to be reliable.
Hamas's 7 October attack on Israel resulted in 1,206 deaths, mostly civilians, according to an AFP tally of Israeli official figures.
