TEHRAN — This week witnessed one of the most intense episodes in the recent escalating cycle of violence between Lebanon's Tehran-backed Hezbollah movement and Israel, in which Ibrahim Akil, a wanted senior elite force commander of the Shiite group, was killed in south Beirut Israeli strike, alongside several other senior members.

The attack was preceded by a chain of communication devices blasts across Lebanon that left at least 37 dead, most of them Hezbollah militants, with nearly 4,000 others injured.   

The ongoing conflict has raised questions regarding whether Tehran will ultimately engage in a direct conflict with Israel to shore up Hezbollah or maintain restraint, a policy it has largely adopted since the outbreak of the Gaza war over the past year. 

On Thursday, Maj. Gen. Hossein Salami, the commander of Iran's Islamic Revolutionary Guard Corps (IRGC), condemned the pager blasts, blaming the sophisticated attacks on Israel. In an open letter to Hezbollah leader Hassan Nasrallah, the hard-line commander pledged an "overwhelming response." Salami, however, refrained explicitly from making any promise of Iranian involvement in such retaliation.
