Every year Moscow have a major terror attack.....before it was the metro,now the airport's.It's actually pretty scary but it's hard to base your security around securing the airports, metro stations, etc. Why is it that terrorists don't bomb the security lines here at American airports? Two things come to mind. First, Al Qaeda has never directly target the average American civilian (which terrorists in Russia seem to be more than happy to do, and Al Qaeda did in Spain and London iirc). Second, there are so few terrorists here that most of them would get caught trying to plan an attack, rather than when they try to carry it out.
Since the 2000's the terrorism attacks spread to all Russia.
