Russia launched multiple missiles in the Black Sea during a naval exercise. Vladimir Putin attended the maneuvers from the Marshal Ustinov missile cruiser. The Navy said the drills involved warships from Russia’s Black Sea Fleet along with several ships from its Northern Fleet.

The Russian naval maneuvers come amid heightened U.S.-Iran tensions after a U.S. airstrike last week killed Iran’s most powerful military commander.

As part of the Black Sea drills, MiG-31 fighter jets launched Kinzhal hypersonic missiles at practice land targets. Navy ships performed several launches of Kalibr cruise missiles and other weapons.

More than 30 warships and 39 aircraft, including several Tu-95 strategic bombers, took part in the exercise.
