Iran's Revolutionary Guard Corps launched military drills on Saturday, in defiance of newly imposed sanctions put forward by the United States.
In a statement posted on its official website, the elite military body said the manoeuvres in the northeastern province of Semnan were aimed at demonstrating Iran's "complete preparedness to deal with the threats" and "humiliating sanctions" from the White House.
"We are working day and night to protect Iran’s security," head of Revolutionary Guards' aerospace unit, Brigadier General Amir Ali Hajizadeh, said to a local news agency, as reported by Reuters news agency.
"If we see smallest misstep from the enemies, our roaring missiles will fall on their heads.On Friday, US President Donald Trump's administration imposed sanctions on Iran after the Islamic Republic confirmed that it had test-fired medium range-missiles last Sunday.
The White House said the move violated a Security Council resolution proscribing missiles that could carry a nuclear device.
