"People of the region of Arab and Islamic countries who are living under the brutality of ISIS, including Lebanon which suffered a few days ago from it, are the most aware and sympathetic of what hit the French nation last night," Nasrallah said in a televised address.
He also offered condolences to the victims of Saturday's attacks in Paris.
"We offer our deep condolences, solidarity, sympathy, moral and humanitarian stand to those innocents who are invaded by the barbaric criminal management of ISIS," Nasrallah said.
"If they assume killing our men and women and children and burning our homes and markets will shake our will and determination, they are wrong. It will increase our determination. We fought ISIL [IS] and other groups on several fronts, and after this we will search for [IS] on open fronts and fight them there," Nasrallah said in a televised address Saturday night, as quoted by the Al Jazeera network.
On Thursday, twin blasts hit Beirut's Burj al-Barajneh neighborhood, which is a stronghold of the Hezbollah movement. At least 43 people died and 239 were injured, according to the Red Cross. The IS claimed responsibility for the attack.
On Friday night, eight extremists wearing explosive belts attacked several venues across Paris, killing 129 people at restaurants, the Bataclan concert hall and in the vicinity of the Stade de France stadium. The IS also claimed responsibility for those attacks.
Hezbollah, a paramilitary and political organization originating in Lebanon's Shiite population, was established in the 1980s. The group has been fighting alongside the Syrian government against the Islamic State (IS) Sunni radicals and other militant groups since 2011.
