MOSCOW — Russian Prime Minister Vladimir Putin vowed retribution for the suicide bombing attack at Russia's busiest airport that killed 35 people.
Putin, who has built much of his reputation on harsh statements, said Tuesday that "retribution is inevitable" for the Monday attack at Domodedovo Airport, which left another 180 people injured.
Russian news agencies that reported his comments did not say whether he specified what kind of retribution or against whom.
No claims of responsibility have been made for the attack. However, suspicion is likely to fall on Islamist separatist insurgents from Chechnya or elsewhere in Russia's restive Caucasus region.
