Also: U.S. intelligence also warned last month that terrorists could attack a Moscow synagogue. A day after receiving the warning, on March 7, Russia’s Federal Security Service (FSB) announced that it had prevented an attack on a Moscow synagogue by an ISIS-K cell.

[...] Three days before the Crocus City Hall attack, Russian President Vladimir Putin had dismissed the U.S. warnings, calling them “outright blackmail” and attempts to “intimidate and destabilize our society.”

Putin and other Russian officials have made no mention of the U.S. intelligence supplied in relation to the planned synagogue attack.
