Israel's spy chief on Wednesday vowed to make Hamas pay for its attacks on Israel, after a drone strike attributed to Israel killed the group's deputy chief Saleh al-Aruri in Lebanon.
The Mossad spy agency "is committed to settling the score with the murderers who descended upon the Gaza envelope on October 7" and with Hamas's leadership, David Barnea said.
"It will take time, just like after the Munich massacre, but we will lay our hands on them wherever they will be."
Barnea spoke at the funeral of former Mossad chief Zvi Zamir, who oversaw Israel's retaliation against Palestinian militant groups in the aftermath of the 1972 murder of Israeli Olympic athletes in Munich.
His remarks came a day after Aruri, the deputy political chief of Hamas, was killed in a drone strike in a southern Beirut suburb.
Senior Lebanese officials accused Israel of carrying out the strike. Israel has not claimed responsibility.
Israel has waged a nearly three-month-long war against Hamas in the Gaza Strip after the Palestinian militant group launched the October 7 attack on southern Israel that resulted in the deaths of at least 1,140 people, according to an AFP tally based on the latest Israeli figures.
"Every Arab mother ought know that if her son participated, directly or indirectly, in the slaughter of October 7, his blood shall be upon his own head," Barnea said.
Israel's retaliation has claimed the lives of at least 22,313 Palestinians in the Gaza Strip, according to the health ministry in the Hamas-run territory.
That figure does not specify the number of Hamas militants killed in the fighting, but Israel contends that at least 8,000 Hamas fighters are among the dead.
