Russia fired several anti-ship missiles in the Sea of Japan, according to its defense ministry.

Moscow said Tuesday its military was conducting a simulated missile attack, involving two of its boats firing on a mock enemy warship about 60 miles away.

Russia's Defense Ministry said the target was successfully hit by two Moskit cruise missiles. The Moskit, whose official NATO-designated name is the SS-N-22 Sunburn, is a supersonic anti-ship cruise missile that can carry conventional payloads or nuclear warheads.

The ministry said the exercise took place in the Peter the Great Gulf, a waterway along Russia’s eastern border in the Sea of Japan. The Kremlin did not give more precise coordinates.

The gulf acts as the Russian Pacific Fleet headquarters at Fokino and is approximately 430 miles from Japan's northern Hokkaido Island.

Japanese Foreign Ministry Tasuku Matsuki said Japan does not plan to lodge a protest over the missile exercise as the location where it was carried out — Peter the Great Bay — is considered Russian coast, although the water is between the two countries.

"On the whole, Japan is concerned about Russia’s increasing military activities around the Japanese coasts and watching them with great interest," Matsuki said.

Russian forces have conducted similar missile drills in that area in the past and issued maritime advisories ahead of time.

The Japanese foreign minister did not comment on Russia’s intention of the exercise.

The Indo-Pacific region remains tense as Russian nuclear-capable Tu-95 bombers flew over the Sea of Japan for several hours last week, North Korea has conducted its own ballistic missile tests in the sea and the U.S. and China have mobilized several ships in the surrounding areas. Also, the U.S. and South Korea participated in their springtime joint military drills, which included the flighting of a B-52 bomber over the Korean Peninsula.

In September, Japan protested military exercises Russian held on the Kuril Islands — some of which are claimed by Japan. Tokyo has similarly expressed concern about Russian and Chinese warships conducting shooting drills in the Sea of Japan.

The two police officers who fatally shot the suspect of the Covenant School shooting in Nashville on Monday have been identified.

Officer Englebert is a four-year MNPD veteran and Officer Collazo is a nine-year MNPD veteran.

According to the police chief, Hale fired at the officers who were arriving at the scene from windows on the second floor before they swept the building and found her in a common room.

"The first call to 911 about shots being fired in the building came in at 10:13 a.m. Officers rushed to the campus, made entry, and began clearing the building. Shots were heard coming from the second level. It was on the second floor, in a common area, that a team of officers encountered Hale shooting (she had been firing through a window at arriving police cars). Two members of an officer team fired on Hale and fatally wounded her," Chief Drake said.

The responding officers were on the scene and neutralized the shooter within 15 minutes of the initial shots being fired by Hale.

The victims were identified as Evelyn Dieckhaus, William Kinney, and Hallie Scruggs, all age nine, as well as Mike Hill, 61, Cynthia Peak, 61, and Katherine Koonce, 60.

According to the police, Hale, who attended the school years ago, arrived on campus in her Honda Fit and was heavily armed with three guns. They included two AR-style weapons and a pistol.

Surveillance video released by MNPD showed Hale shot her way into the church/school through a set of glass doors at a side entrance of the building.

The MNPD also found writings belonging to Hale in a nearby vehicle that revealed her attack was "calculated and planned."

Other evidence, including a sawed-off shotgun and a second shotgun, was seized when officers executed a search warrant at Hale’s Brightwood Avenue home, police said.

The shooting remains under investigation and is being led by several MNPD components, with assistance from the Tennessee Bureau of Investigation, the Federal Bureau of Investigation, the ATF and Tennessee Highway Patrol.
