Russian Prime Minister Vladimir Putin vowed "retribution is inevitable" for the suicide bombing that killed 35 people at Russia's busiest airport, while President Dmitry Medvedev demanded robust checks at all transport hubs.
"This was an abominable crime in both its senselessness and its cruelty," Putin told a meeting of ministers.
"I do not doubt that this crime will be solved and that retribution is inevitable. The task of the government is to extend support to the families of the dead and injured."
No claims of responsibility have been made for the attack, which also left 180 people injured. However, suspicion is likely to fall, however, on Islamist separatist insurgents from Chechnya.
