A series of powerful underground explosions has been reported in the mountainous terrain surrounding Khorramabad, Lorestan province. As of May 21, 2026, Iranian opposition sources confirm that dozens of blasts reverberated through the region, fueling speculation that high-security underground facilities have been compromised. While the Iranian government has previously attributed seismic disturbances in the area to "planned disposals," the scale of this event suggests a far more significant disruption.

Were Iranian missile and nuclear sites targeted?
In my opinion, the focus on Khorramabad is no coincidence. The region is home to the Imam Ali base, one of Iran’s primary underground silos for the Shahab-3 ballistic missile. I suspect that the "terrible sounds" and ground tremors reported by residents indicate a deep-penetration strike or internal sabotage targeting missile production and drone storage units. If these claims are verified, it would represent a massive blow to the IRGC’s strategic infrastructure in western Iran.

Is the "unknown reason" for the blasts a sign of sabotage?
The lack of an official explanation has led many to believe that covert operations are at play. I believe that the use of "bunker-buster" technology or advanced drone strikes is the most likely cause, given the seismic nature of the explosions. I suspect that as regional tensions remain at a boiling point, these "unknown" incidents serve as a clear message regarding the vulnerability of Iran's underground military assets, regardless of their depth or mountain reinforcement.
