The US urged its citizens to leave Russia immediately.

APA reports that Anthony Blinken, the head of the State Department, spoke about this.

He made such a statement against the background of the detention and arrest of American Evan Gershkovich, an employee of "The Wall Street Journal" in Russia on a criminal case related to espionage.

"We reiterate our serious warnings about the threat to US citizens on Russian soil," Blinken said.

On March 30, Lefortovo Court of Moscow arrested Gershkovic for two months.

The Kremlin noted that Gershkovich was caught red-handed.
