Homegrove yeah they have. US intelligence had most of the details right, just the date was wrong.
Dubman Heard this on the radio both US and UK told Moscow that an attack was imminent but they chose to ignore it
Kinda, but not quite. The US posted their warning on 7 March about something possibly happening within 2 days, and Russia did then within 48 hours appear to nullify a planned ISIS attack.
Clearly there were more attacks in the pipeline though than the US initially briefed about - which was also suggested at the time - but Russia wasn’t able to pick up on all of them.
