Images of the facility taken Tuesday, a day after the reported explosion which killed at least two people at the secretive Parchin plant, showed that several buildings at the location sustained heavy damage and some even collapsed, Channel 2 reported.

The photos “clearly show damage consistent with an attack against bunkers in a central locality within the military research complex at the Parchin military compound,” Israel Defense wrote.

The images were taken by the French satellite Pleiades the morning following the blast, the source of which remains unknown.
