At least 35 people were killed at Russia's largest airport. President Medvedev has vowed to capture and punish the culprits behind the bombing, which also injured about 130 people during the busy late afternoon at Domodedovo Airport in Moscow. "The explosion was right near me, I was not hit but I felt the shock wave -- people were falling," said Yekaterina Alexandrova, a translator who was waiting to meet a client flying in from abroad.
"I heard a loud boom... we thought someone had just dropped something. But then I saw casualties being carried away," said a check-in attendant who gave her name as Elena.
Medvedev has delayed his departure for the Davos international business conference in Switzerland.
No group has yet taken responsibility for the attack, but dozens of Internet surfers, writing in Russian, praised the suicide bomber on unofficial Islamist site kavkazcenter.com.
