Without speculating too much, I do want to comment on the train crash that occurred last week between Moscow and St. Petersburg.
Although this is no longer "front-page" news in certain places (such as the U.S.), keep in mind that this was a fairly serious event.
The BBC News reported today that an Islamist group has taken responsibility for the attack. Investigations continue. The injured are recovering; funerals are being performed this week.
It's uncertain what role the incident will play in future politics and relations between religious groups. But keep in mind that if you have friends in Russia, this might be something they've been thinking and possibly worrying about in the past few days.
