Hezbollah said it launched a salvo of missiles at an Israeli military base on Saturday, as Israeli troops battled militants in Lebanon and Gaza on Yom Kippur, the holiest day in the Jewish calendar.
Cities around Israel were quiet with markets closed, flights stopped and public transport halted as observant Jews fasted and prayed on the Day of Atonement.
But with the country at war against Hezbollah and Hamas, troops remained engaged in combat on the northern and southern frontiers amid a firestorm of criticism over the wounding of four UN peacekeepers in Lebanon.
Hezbollah, which has lost its leader and a long list of key commanders to Israeli strikes since the start of the war in Lebanon, on Saturday said it struck an army base with missiles to the south of the city of Haifa.
Hezbollah fighters were "targeting the explosives factory there with a salvo of... missiles", the group said in a statement.
Air raid sirens sounded on Saturday in northern Israel, with the Israeli military saying it had intercepted a projectile launched from Lebanon.
In the hours ahead of Yom Kippur, Israel faced severe diplomatic backlash over what it said was a "hit" on a United Nations peacekeeping position in Lebanon.
Two Sri Lankan peacekeepers were hurt in the second such incident in two days, the UNIFIL mission said Friday.
The military said Israeli soldiers had responded with fire to "an immediate threat" around 50 metres (yards) from the UNIFIL post.
As Israel faced a chorus of condemnation by UN chief Antonio Guterres, Western allies and others, the military pledged to carry out a "thorough review".
UNIFIL peacekeepers in Lebanon have found themselves on the frontline of the Israel-Hezbollah war, which has killed more than 1,200 people in Lebanon since September 23, according to an AFP tally of Lebanese health ministry figures.
Four peacekeepers have been injured including two Indonesians who were hurt on Thursday when an Israeli tank shot at their watchtower, according to UNIFIL.
Sean Clancy, the Irish military's chief of staff, said he did not believe Israel's explanation of Friday's incident.
"So from a military perspective, this is not an accidental act," said Clancy, whose country has troops in UNIFIL.
French President Emmanuel Macron said he believed the UN peacekeepers had been "deliberately targeted".
Guterres condemned the firing as "intolerable" and "a violation of international humanitarian law," while the British government said it was "appalled".
US President Joe Biden said Friday he was "absolutely" asking Israel to stop firing at UN peacekeepers.
The incidents came more than two weeks into Israel's war with Iran-backed Hezbollah in Lebanon, which has seen Israeli warplanes conduct extensive strikes and send ground troops across the border.
Diplomatic efforts to negotiate an end to the fighting have so far failed, but Lebanese Prime Minister Najib Mikati said his government would ask the UN Security Council to issue a new resolution calling for a "full and immediate ceasefire".
Lebanon's military said on Friday that an Israeli strike on one of its positions in south Lebanon killed two soldiers.
After the Yom Kippur holiday, attention is likely to turn again to the expected retaliation against Iran, which launched around 200 missiles at Israel on October 1.
Israeli Defence Minister Yoav Gallant vowed this week that his country's response would be "deadly, precise and surprising" with Biden's administration pushing for a "proportionate" response that would not tip the region into a wider war.
Biden has urged Israel to avoid striking Iranian nuclear facilities or energy infrastructure.
Iran-funded Hezbollah began firing on Israel in support of its Palestinian ally Hamas following the October 7, 2023 attack on Israel which resulted in the deaths of 1,206 people, mostly civilians, according to an AFP tally based on official Israeli figures, which includes hostages killed in captivity.
Israel's military campaign immediately after the attack has wrought devastation on Gaza and, according to data from the health ministry in the Hamas-run territory, killed 42,126 people, mostly civilians.
Israeli operations in Gaza continue, with the army laying siege to an area around Jabalia in northern Gaza last weekend, causing fresh suffering for hundreds of thousands of people trapped there, according to the UN agency for Palestinian refugees
"The bombardment has not stopped. Every minute there are shells, rockets and fire on the buildings and everything that moves", Areej Nasr, 35, told AFP after fleeing from Jabalia camp to Gaza City Thursday.
On Friday, Gaza's civil defence agency reported 30 people killed in Israeli strikes in the area, including on schools being used as shelter by displaced people.
An AFP journalist in Gaza reported heavy artillery shelling, explosions and gunfire Saturday further south in Gaza City's Zeitoun neighbourhood.
