Iran revealed a previously unseen Unmanned Aerial Vehicle (UAV) base in a new video released Sunday, coming amid rising tensions with Washington.

The clip shows a long line of UAV's parked on the tarmac at an undisclosed air base.

Iran is estimated to have considerable UAV capabilities, but Sunday is the first time it has ever revealed its UAV's base.Tensions have been rising between the Islamic Republic and Washington ever since President Trump instituted new sanctions in July over its ballistic missile program.

Iran also announced on Saturday that it was testing its new Bavar-373 air defense system, which it claims rivals the Russian S-300.
