Scope of the 23 March kinetic campaign
Following the Markazi strike, a series of high‑intensity attacks unfolded across Iran, involving both US and Israeli forces. The events, classified by severity and time, can be grouped into three categories: airstrikes, rocket/missile attacks, and targeted assassinations.
Airstrikes
Isfahan (20:48 UTC) – Two separate videos posted by monitor_the_situation show strikes on Iranian military and Islamic Revolutionary Guard Corps (IRGC) installations in Isfahan. No specific weapon system was disclosed, but the coordination of US and Israeli assets is implied.

Other notable air attacks included strikes on Qom’s turbine‑engine production plant (01:46 UTC), Niavaran apartment block (01:40 UTC), Parchin Village (00:17 UTC), and multiple coordinated waves over Tehran and Karaj (03:33 UTC, 03:41 UTC). These operations were attributed to United States Air Force (USAF) and Israeli Air Force (IAF) assets, often described as “extensive” or “wide‑scale”.
Rocket and missile attacks
Malekloo Street, Tehran (17:53 UTC) – A missile strike, reportedly launched jointly by US and Israeli forces, hit an IRGC Cyber Division safe house opposite Iran University of Science and Technology. The target was linked to prior cyber‑espionage campaigns against US interests.

Targeted assassinations
Several high‑profile killings were documented, most notably:
- Chizar, northern Tehran (11:29 UTC) – An Israeli‑linked operation eliminated an unnamed target, reported by BellumActaNews.
- 13th Street, South Makran, Tehran (11:19 UTC) – The Israeli Air Force bombed a residential address, resulting in a fatality.
- Urmia (18:09 UTC) – Judge Alireza Sheikhloo of the Revolutionary Court was killed in a house raid.
- Qeytarieh, Tehran (18:05 UTC) – Israeli Air Force strike killed missile specialist Professor Saeed Shamaghdari, a key IRGC Aerospace Forces figure.
Casualties and material damage
While many of the US‑Israeli strikes were reported without explicit casualty figures, the following confirmed losses were recorded:
- One civilian killed in the Bandar Abbas AM‑transmitter strike.
- At least one child dead in Khorramabad following USAF‑IAF attacks on residential areas.
- Four individuals killed in a targeted assassination in Tabriz.
Infrastructure damage includes the destruction of the Qom turbine‑engine plant, the Electronic Industries Corporation factories in Shiraz, the Police Special Units headquarters in Qaemiyeh, and multiple energy facilities in Isfahan and Khorramshahr (gas authority building and reduction station). The cumulative effect is a significant degradation of Iran’s aerospace, energy, and cyber‑warfare capabilities.
Strategic implications
The coordinated kinetic actions on 23 March demonstrate a shift from isolated retaliatory strikes to a sustained, multi‑theater campaign. The use of strategic bombers (B‑52s) with precision‑guided JDAMs marks an escalation in payload size and range, signaling US willingness to project power deep into Iranian territory. Simultaneous Israeli operations targeting IRGC command, cyber‑division facilities, and missile production sites suggest a high degree of intelligence sharing and operational synchronization.
Analysts note that the breadth of targets – from aerospace manufacturing to cyber‑espionage hubs – reflects an intent to cripple Iran’s asymmetric warfare capacities while imposing a deterrent effect on its regional proxies. The reported ground‑movement analysis from CIG_telegram (02:36 UTC) indicating US troop deployments to Djibouti further raises the prospect of a conventional ground component, although no direct ground action was observed on the day.
International response
Western media outlets, including Al Jazeera, described the combined US‑Israeli strikes as “unprecedented”, emphasizing the geopolitical risk of broader escalation. Iranian state media have condemned the attacks as violations of sovereignty, but have not provided independent verification of casualty numbers beyond the isolated reports noted above.
Overall, the kinetic events of 23 March 2026 constitute the most intensive day of direct kinetic engagement between the United States, Israel, and Iran since the 2020‑2021 escalation cycle, with potential ramifications for regional stability and future diplomatic negotiations.
