Five civilians, all Syrians and including three children, were killed in Israeli strikes in Lebanon on Tuesday and at least three Lebanese civilians were killed the day before, according to state media and security sources.
"Continuing to target civilians will push the Resistance to launch missiles at settlements that were not previously targeted," Nasrallah said, in comments made during a televised address to mark the Shi'ite holy day Ashoura.
Hezbollah, an Iran-backed militant group, refers to all Israeli population centres as settlements and does not recognise Israel.
Israel and Hezbollah have been trading fire since Hezbollah announced a "support front" with Palestinians shortly after its ally Hamas attacked southern Israeli border communities on Oct. 7, triggering Israel's ensuing military offensive in Gaza.
Iran-aligned groups in the region, including Shi'ite armed factions in Syria and Iraq and Yemen's Houthis, have also been firing on Israel since shortly after Oct. 7.
In Lebanon, the fighting has killed more than 100 civilians and more than 300 Hezbollah fighters, according to a Reuters tally, and led to levels of destruction in Lebanese border towns and villages not seen since the 2006 Israel-Lebanon war.
Nasrallah promised that totally or partially destroyed homes would be rebuilt "more beautiful than they were before."

Smoke rises behind buildings from an Israeli strike against a Hezbollah target on the town of Aita al Chaab on June 30, 2024 in Rmaich, Lebanon. Hezbollah and the Israeli Defense Forces (IDF) have been trading cross-border fire since the October 7 attacks, with the conflict escalating in May when the group launched a missile-carrying drone against Israel for the first time. The conflict intensified in June when Hezbollah fired hundreds of rockets and drones at Israeli military sites following the killing of senior commander Taleb Abdullah. This marked the largest assault since October 8. The last significant conflict between Israel and Hezbollah occurred in 2006, lasting 34 days and resulting in a stalemate (Photo by Chris McGrath/Getty Images)
