“We pledge to our great martyr and his martyred brothers to continue the path of resistance and jihad until achieving its goals of freedom and victory,” Hezbollah said in a statement.
The announcement came a day after the Israeli military officially claimed Safieddine had been killed in the attack, which used bunker-buster bombs similar to the strike that killed Nasrallah on September 27.
Israel has intensified its attacks both on Gaza and Lebanon.
Gaza government media office said on Wednesday that the regime has killed more than 770 Palestinians and wounded 1,000 others after 19 days of attacks and siege on Jabalia, in northern Gaza.
The regime’s attacks on Lebanon also claimed the lives of nearly 30 people in 24 hours, according to an announcement by Lebanon’s government. At least 2,570 Lebanese have been killed in Lebanon since October last year.
