Though no claims of responsibility have been made for Monday's deadly suicide bombing that shook Russia's busiest airport and killed 35, international outcry over the attack has already been resounding.
Russian Prime Minister Vladimir Putin vowed retribution, while President Dmitry Medvedev demanded robust security checks at all transport hubs.

Unfortunately for Moscow, the attack is only the recent in a turbulent era for the nation. In 1999, a chain of apartment block explosions killed a total of 230 people, while 130 lives were lost in the infamous Dubrovka Theatre attack in 2002.
