The United States military attache has been summoned to the Russian Defense Ministry.

APA reports quoting TASS that the statement came from the Russian Defense Ministry.

The military attache was summoned to the ministry because of the presence of an American Virginia-type nuclear submarine in a training area planned by the Pacific Fleet near Urup Island.

"The Russian Defense Ministry has summoned a US military attache in connection with the violation of the state border of the Russian Federation by a US Navy submarine," the statement said.

Despite repeated warnings to the crew of the submarine, they ignored it.
