You see it turns out that any terror attack is a"natural response to authorities’ lawlessness and crimes of totalitarian regime". Haven’t you known about that? Any terrorist is aware about that. Usually that’s their main excuse for any terrorist incident and for... some Russian opposition guy called Kas’yanov either. Recently he told such a thing to Estonian newspaper Postemees about explosion in Minsk. So there is despotism in UK, and Spain, and USA, and in many other countries suffered from terrorist attacks. You had that coming living in tyranny, guys. Earlier I thought that Russians are fighting against terror as any other sensible country. But there is a black sheep in every fold. And seems like back sheep Kas’yanov has volunteered to be terrorist voicer. I guess that he must to be quite a well-known politician if foreign editions are interesting in his opinion. And this man is making no bones for demonstrating his relation to extremists. I would quarantine such people in some special facilities for their open support and advocacy of world terrorism.
