At least one person was lightly injured early Friday afternoon two separate barrages, with a total of approximately 130 missiles, were launched towards northern Israel.
Magen David Adom (MDA) teams are searching a number of locations for victims.
The barrages have sparked a number of fires in the area.
Following the barrages, Hezbollah announced that it had fired rockets towards an IDF base in Birya, in response to IDF strikes on villages in southern Lebanon.
The IDF is now striking in southern Lebanon.
The IDF confirmed: "Following the sirens that sounded over the past few hours in the areas of the Golan Heights, Safed and the Upper Galilee, approximately 120 launches were identified crossing from Lebanon into Israeli territory."
"The IDF Aerial Defense Array successfully intercepted some of the launches. Fallen projectiles and fallen shrapnel from the interceptions were identified in several areas. Fire and Rescue Services are currently operating to extinguish fires that were caused by fallen projectiles in several areas.
"Following the sirens that sounded in the areas of Meron and Netu'a, approximately 20 launches were identified crossing from Lebanon into Israeli territory. Most fell in open areas. No injuries were reported."
The statement continued, "Earlier today, IDF soldiers identified a Hezbollah terrorist entering a terrorist infrastructure site used by Hezbollah in the area of Kfarkela in southern Lebanon. Swiftly, the IAF struck the site from which the terrorist was operating."
"Additionally, the IAF struck Hezbollah terror infrastructure in the areas of Aitaroun, Kfarkela, Meiss El Jabal, Tayibe, Odaisseh, and Yaroun in southern Lebanon.
"IDF artillery struck in a number of areas throughout southern Lebanon."
The IDF also stressed that it "will continue to operate against the threat of the Hezbollah terrorist organization to defend the State of Israel."
