Iran reveals huge underground missile silo

Iran has revealed an underground missile bunker packed with bombs in footage broadcast on its state television network as a rousing message to its people.

The clip shows a long tunnel deep under the earth stuffed full of weapons, trucks and parts appearing to belong to the Qiam-1 ballistic missile system. Outside the grand entrance to the bunker hang huge posters of Supreme Leader Ayatollah Ali Khamenei and President Hassan Rouhani.

Below it, sliding doors pull away and a ramp drops to allow access to the dimly-lit tunnel. The footage cuts to soldiers removing the casing from part of a weapon using a motorised crane, before attaching it to the lower half of the bomb. It is mounted on a trolley and moved to a cavernous area where it is winched up to point towards the sky.

Chaotic scenes then shows the missile fired, with the camera in the tunnel engulfed in flames and smoke. An exterior shot - from the surface - sees the missile leave through a spherical hole in the ground before rocketing away from the desert location.
