Iranian state media showed off a fleet of drones lined up inside an underground bunker as part of a chilling propaganda video.

Footage released by the semi-official Fars News Agency shows the unmanned fleet sitting on rocket launchers and on truck beds, while dramatic music plays in the background.

Drones lined either side of an aisle leading down a brightly lit tunnel with a variety of Iranian flags.

Cheaper Shahed drones, which cost only a few thousands of dollars to make, are thought to be the drones showcased in the clip, according to the Daily Mail.
