43-year-old Uri Peretz was killed in Nahariya on Thursday by a direct hit after Hezbollah launched a wave of rockets at northern Israel, injuring twenty-five additional people.
Peretz was listed as in critical condition by Magen David Adom teams before being pronounced dead.
Another man, aged about 50, is in critical condition, according to an MDA spokesperson.
There are at least three impact sites, according to Israeli media, with damage reported to gas infrastructure and a house in Moshav Margaliot suffering minor damage.
Additionally, Nahariya's municipality reported several burning vehicles as a result of the Hezbollah attacks.
"I arrived at the scene within a few minutes and saw extensive destruction, smoke, shattered glass, and a lot of commotion," said MDA paramedic Omri Gorga.
"We joined an MDA paramedic who was treating the injured man, a man about 50 years old who was lying on the floor with shrapnel in his limbs," said MDA emergency medical technician Oshri Abutbul.
In addition to the Hezbollah attack, sirens sounded twice in central Israel later on Thursday after ballistic missile launches from Iran.
No injuries were reported, and both barrages were intercepted.
Hezbollah fired a barrage of rockets at northern Israel on Thursday evening, and Israeli media reported that fragments impacted a building in the town of Jadeidi-Makr.
Six injured as cluster munition fragments hit central Israel
At least six people in central Israel were wounded by cluster munition fragments earlier on Thursday amid an intense wave of Iranian missile barrages.
MDA provided treatment to a woman in her 40s in Tel Aviv suffering from upper-body shrapnel injuries. She was rushed to Sourasky Medical Center's Ichilov Hospital with light injuries, MDA said.
Paramedics also provided treatment to a 26-year-old man who was also lightly injured by shrapnel in the Tel Aviv area.
Additionally, the Technion-Israel Institute of Technology's campus was hit by falling shrapnel, the university stated. The campus is located in the Haifa Naveh Sha'anan area.
In addition, at least two people were injured when shrapnel hit in Samaria, the Sha'ar Shomron local council announced.
