Situated 60km southeast of Tehran, Parchin is a sensitive military site housing several industrial and research units, where Western security services believe Iran carried out tests related to nuclear bomb detonations more than a decade ago.

In 2015, Tehran allowed the UN nuclear watchdog to take environmental samples at the military site to make an assessment of "possible military dimensions" of Iran's nuclear program.

Iran says its nuclear program is solely for peaceful purposes.

In June 2020, an explosion caused by a tank leak occurred in the same area at a gas storage facility.
