WASHINGTON, March 22. /TASS/. The US Administration is attempting to get more information about the incident in the Crocus City Hall in the Moscow Region and called it a terrible attack, White House National Security Communications Advisor John Kirby said at a regular briefing.

"We're trying to get more information but really would refer to Russian authorities to speak to it. The images are just horrible. And just hard to watch and our thoughts obviously are going to be with the victims of this terrible, terrible shooting attack," Kirby said.
