The Pentagon has warned Iran that it will use a new bomb against it in case of a military conflict.
According to Deputy Commander of the US Air Force General Herbert Carlisle, the new 13.5 ton bomb which entered the US armed forces last year is designed to destroy underground secret facilities that allegedly exist on the territory of Iran.
Last week US Secretary of Defense Leon Panetta published a magazine article in which he admits that the Pentagon is planning a military operation against Iran.
Western countries suspect Iran of developing nuclear weapons.
Tehran claims that its nuclear program pursues peaceful purposes.
