Iran broadcast footage of an underground missile facility filled with missiles and launcher units, according to state media.
CNN reported that the images from the The Islamic Revolution Guards Corps (IRGC) Aerospace Force showed an underground tunnel allegedly located 1,640 feet under a mountain. An Iranian general said that the tunnel is one of "numerous missile bases" in the country.
"The missiles in various ranges are mounted on the launchers in all bases and [are] ready to be launched," Brig. Gen. Amir Ali Hajizadeh was quoted by state media reports as saying.
Hajizadeh said that Iran would not begin a war but that "if enemies make a mistake, missile bases will erupt like a volcano from the depth of earth," AFP reported. The senior general also said that the missiles would be fired at the command of "the supreme commander-in-chief," or Ayatollah Ali Khamenei.
Iran is developing new weapons to advance its missile technology, according to Hajizadeh.
"As of next year, a new and advanced generation of long-range liquid and solid fuel missiles will replace the current products," Hajizadeh said.
The footage of the missile facility comes just days after Iran announced via state media that it had test fired a new domestically produced ballistic missile, a move that U.S. Ambassador to the United Nations Samantha Power said Wednesday violated U.N. Security Council resolutions.
White House press secretary Josh Earnest said Tuesday that there were "strong indications" that the test constituted such a violation. An unnamed Obama administration official told CNN that it likely violated U.N. Security Council Resolution 1929, which blocks Iran from engaging in any activity having to do with ballistic missiles.
The official insisted that the test fire did not violate the nuclear agreement brokered between Iran and world powers this summer. Iran has also said that it did not violate the nuclear deal by test firing the ballistic missile.
"To follow our defense programs, we don’t ask permission from anyone," Iranian defense minister Brig. Gen. Hossein Dehqan said.
