Iran’s Islamic Revolutionary Guard Corps (IRGC) said it carried out a sustained, coordinated strike with Lebanon’s Hezbollah early on March 12, firing a mix of ballistic missiles and armed drones at Israeli population centres and US facilities in the region. The IRGC described the action as the 40th wave of an operation dubbed “True Promise‑4,” saying more than 50 targets were hit over five hours, including sites in Jerusalem, Tel Aviv and Haifa and US bases in Jordan’s Azraq and in the Al Kharj area of Saudi Arabia.
Israeli authorities responded by announcing a “large‑scale airstrike” on Tehran, marking one of the most direct Israeli attacks on the Iranian capital in decades. Israeli air defences intercepted multiple incoming ballistic missiles, scattering debris across central and northern Israel, while Hezbollah’s salvo of roughly 150 rockets struck northern Israel, with many falling in open areas.
The exchange follows a dramatic uptick in hostilities that began when the United States and Israel launched a joint military operation against Iranian targets on February 28. Iran replied with strikes on Israeli territory and regional US facilities, and Hezbollah opened a second front by firing rockets from southern Lebanon. Israeli forces have since intensified air and ground actions in southern Lebanon and carried out strikes on Beirut.
The weapons named by Iranian state and semi‑official outlets — including missiles identified as Kader, Emad, Heibar and Fattah — and the coordinated use of unmanned aerial vehicles demonstrate a deliberate effort to synchronise multi‑domain attacks between Tehran and its principal regional proxy. Israeli officials said they had no prior intelligence that Iranian and Hezbollah launches were part of a planned, integrated operation, underscoring either a lapse in warning or a calculated step‑change in the adversaries’ tactics.
A strike directed at Tehran’s urban area, if confirmed and sustained, would represent a serious escalation from tit‑for‑tat exchanges into a direct inter‑capital confrontation. That carries acute dangers: further militarisation of Lebanon’s front, the widening targeting of US assets across the Gulf, and heavier damage to civilian infrastructure and populations across Israel and Lebanon.
Beyond the immediate battlefield, the confrontation threatens broader strategic and economic fallout. Gulf states hosting US bases may be pulled more firmly into strike and defence calculations, global energy markets could react to heightened risk in key production and transit areas, and international diplomatic channels will face intense pressure to contain spiralling violence.
For now, both sides retain levers of restraint as well as escalation. Israel’s conventional air power and precision strike capability contrast with Iran’s strategic missile and proxy networks, producing asymmetric dynamics that raise the odds of miscalculation in fast‑moving, multi‑theatre engagements. The path ahead is likely to hinge on whether external actors — notably the United States, Gulf partners and European states — succeed in dampening the incentives for further large‑scale strikes or whether reciprocal attacks deepen into a wider regional war.
