Israel has already sent a "clear signal" on this matter.
Israeli intelligence agencies have established a special operations center for tracking and eliminating members of the HAMAS special forces that carried out the attack on Israel in early October, as reported by Sarbaz.kz, citing The Times of Israel and Ynet.
Although the specific targets and operations for elimination are kept secret, the Israeli Minister of Industry has already threatened to pursue Iranian officials who may be involved in planning operations for Hezbollah and HAMAS. He stated that Israel has already sent a "clear signal" on this matter.
The Mossad and Shin Bet (Shabak) have formed a specialized unit named "NILI," which is associated with a quote from the First Book of Samuel ("The strength of Israel will not lie"), as well as the name of a Jewish intelligence organization that operated during the First World War in the interests of Great Britain.
This unit will be responsible for planning and executing operations against Hamas members involved in the attack on Israeli civilian settlements on October 7. It is reported that intelligence agencies already have photographs and names of all the participants in the incursion.
It is noted that the two leaders of HAMAS, Mohammed Deif, the military commander, and Yahya Sinwar, the political leader, are among NILI's top priorities. According to The Times of Israel, Deif and Sinwar are currently hiding in underground tunnels created to withstand bombings initiated after the attacks on settlements and military bases near the border.
It's worth mentioning that Sinwar was one of the founders of Hamas during the First Intifada and was released in a prisoner exchange with Israel in 2011.
