Russian Prime Minister Vladimir Putin vowed on Tuesday to avenge the Moscow airport bombing that killed 35 people, saying that "retribution is inevitable". Putin called Monday's Domodedovo airport bomb blast, which investigators have linked to militants from Russia's predominantly Muslim North Caucasus region, a "brutal and senseless crime".
Russia's powerful prime minister had stayed out of the limelight since the Monday afternoon blast, with President Dmitry Medvedev making a series of televised addresses to the nation that blamed airport security breaches for the attack.
