Retaliation is further fueled by the fact that, less than 24 hours before Haniyeh's assassination, Israel announced—and Hezbollah confirmed—the killing of Hezbollah's senior military commander, Fuad Shukr, in an Israeli airstrike on a Beirut suburb.
According to AFP, Iran and its allied armed groups are preparing coordinated actions intended to “deter Israel while avoiding full-scale war.”
On Wednesday, Iranian officials convened in Tehran with representatives from the "Axis of Resistance" — a collection of proxy forces financed and armed by Iran - to deliberate on retaliation.
A source close to the Lebanese group disclosed to AFP that two scenarios were discussed: a simultaneous response from Iran and militia groups, or a staggered reaction from each party. This source, who had been briefed on the meeting, requested anonymity due to the sensitive nature of the information.
Iran's Supreme Leader, Ali Khamenei, has threatened "harsh punishment" for Haniyeh's killing, which the group attributes to Israel, and has vowed revenge.
