"When it happens, we see authorities react. They give instructions and order intensive antiterrorist operations, but it all comes to naught until we are shaken by the next explosive terrorist act," he said.
Chechen warlord Doku Umarov, one leader of the new wave of Islamist militants who have supplanted the Chechen separatists of the past, claimed responsibility for the Moscow metro bombings and is widely cited as a suspect in Monday's Domodedovo blast.
But most Russian press coverage appears to agree that it was probably a male attacker who detonated the equivalent of 7 kilograms (15.4 pounds) of TNT in Domodedovo's international arrivals area Monday, killing at least eight foreign citizens along with more than two dozen Russians.
President Dmitry Medvedev slammed lax security measures and promised that the terrorists would be caught and punished. After canceling his plans to attend the Davos International Economic Forum, Mr. Medvedev decided to deliver his previously scheduled address on global economic reform on Wednesday, then return immediately to Moscow.
