Russian Prime Minister Vladimir Putin promised revenge for the bombing of Moscow's Domodedovo airport Monday that left at least 35 people dead. "This was an abominable crime in both its senselessness and its cruelty," said Putin at a meeting in Moscow. Russian President Dmitry Medvedev blamed airport officials for what he saw as a security breach and said, "Everything must be done to find, expose and bring the bandits who committed this crime to court." Both leaders have been visiting victims of the attack in the hospital. Over 100 people were injured in the suicide bombing.
