According to unofficial reports, the explosion that took place last night at the Perchin military facility near Tehran was due to an attack by unidentified UAVs.
The facility in Perchin is one of the most important centers of Iran's nuclear and missile industries, and in 2020 a report was published that a significant explosion had occurred there.
Perchin is a town in southeastern Tehran. According to intelligence sources, Iran's important defense industries are concentrated in this compound, in addition to missile storage facilities and conventional ammunition.
An Iranian source, however, said that last night, during an "accident" in one of the Ministry of Defense's research units in the Perchin area, engineer Isan Gad Beigi was killed and another colleague was injured.
