The alert places Moscow on heightened security footing amid broader tensions between Washington and Moscow. The warning is specific to a potential attack site but does not establish that an attack is imminent or confirm perpetrators, and available reporting provides no verified casualty figures. Russian authorities’ response and any further security measures remain developing.
