TEHRAN, Iran - A senior commander of Iran's elite Revolutionary Guard says Iran's missiles will come down on the country's enemies if they do wrong.

Gen. Amir Ali Hajizadeh says: "If the enemy does not walk the line, our missiles come down on them."

Hajizadeh's comments come during a military exercise by the Revolutionary Guard aimed at testing its missile and radar systems.

The exercise comes a day after U.S. President Donald Trump's administration imposed sanctions on Iran for a recent missile test. The sanctions target more than two dozen people and companies.
