Research and Education Center President Lt. Col. (Res) Sarit Zehavi has discussed Hezbollah's supreme leader Hassan Nasrallah's recent warnings following the attack which killed Hamas' deputy leader in a rare public address.
"I think that Nasrallah will continue to drag Israel into war," Ms Zehavi told Sky News Senior Reporter Caroline Marcus.
"I can say that this morning, there was a killing of a Hezbollah military operative, which is relatively more senior than the others who were killed.
"This would be very interesting to see the retaliation of Hezbollah to this ... maybe even more interesting than to the killing of a Hamas senior."
Hezbollah's supreme leader Hassan Nasrallah warned the Lebanese terror group "cannot be silent" and is "ready for a war without limits" in the wake of the assassination of Hamas deputy leader in Beirut on Tuesday.
Israel has not claimed responsibility for the attack but is largely believed to be behind the killing.
