MOSCOW, March 25. /TASS/. Kremlin Spokesman Dmitry Peskov refused to comment on whether the terrorist organization Islamic State (banned in Russia - TASS) might have been involved in the terror attack on Crocus City Hall.

"We have no comment here, as we are not authorized to comment on that," Peskov told reporters, advising them to follow updates from law enforcement agencies.

On the evening of March 22, a terrorist attack rocked the Crocus City Hall music venue in Krasnogorsk near Moscow. According to the Russian Investigative Committee, more than 130 people were killed, and the death toll may rise. Eleven suspects in the terrorist attack have been apprehended, including four shooters who were detained as they were attempting to seek refuge by crossing the Ukrainian border. Russian President Vladimir Putin said in a televised address, citing preliminary information, that the Ukrainian side had prepared "a window" especially for the terrorists to cross the border undetected. He pledged every effort to identify and punish all parties behind the attack and declared March 24 a day of national mourning for the victims.
