The United States military conducted a large-scale airstrike against a major Iranian ammunition depot in the city of Isfahan on Monday night (March 30, 2026)
According to The Wall Street Journal (WSJ), citing US officials, the attack involved the dropping of a large number of approximately 900 kg (equivalent to about 2,000 pounds or 907 kg) bunker bombs, known as penetrating munitions designed to destroy underground or armored structures.
The target was a large stockpile of ammunition located in Isfahan, a strategic city in central Iran that houses both military installations and components of the Iranian nuclear program.
The WSJ reported that the bombs were used in significant quantities to ensure the destruction of protected warehouses.
The attack occurred amid reports that Iran had transferred stockpiles of highly enriched uranium to underground facilities in the same region of Isfahan as a protective measure in the face of escalating tensions.
Although the main target mentioned by American authorities was the ammunition depot, the proximity to sites related to the Iranian nuclear program is noteworthy in the current context of the conflict.
Local witnesses and reports indicate that the bombing generated intense secondary explosions, with visible fireballs launched into the air and felt throughout much of the region.
Images shared on social media and even by President Donald Trump showed the sky over Isfahan illuminated by enormous flames and chain reactions, suggesting that the impact hit stockpiles of explosives or fuel stored at the site.
Context of the escalation
Isfahan is an important hub for Iran: in addition to military bases, the city houses the Nuclear Fuel Research and Production Center, where uranium processing takes place.
In recent weeks, the conflict between the United States, Israel, and Iran has intensified, with exchanges of attacks that include military targets and, in some cases, energy infrastructure.
The use of 900 kg bunker-buster bombs represents a demonstration of American capability to strike fortified and underground targets, a feature frequently discussed in analyses of the Iranian nuclear program, which maintains part of its facilities in deep bunkers for protection against air attacks.
To date, there is no detailed official confirmation from the Iranian government regarding the exact damage or any casualties.
The WSJ based its reporting on American sources, who described the operation as a targeted attack on a “large ammunition depot.”
The action occurs at a time of high regional tension, with discussions in the US about strategies to prevent Iran from advancing toward a nuclear weapon, including the possibility of more complex operations to control stockpiles of enriched material.
This episode reinforces the military escalation in the Middle East and raises questions about the next steps for both Tehran and Washington and its allies.
The situation remains evolving.
