Moscow airport bomb: Dmitry Medvedev seeks shake-up
Dmitry Medvedev spoke out the day after a bomber detonated an estimated 7kg (15lb) of TNT at Domodedovo airport, killing 35 people and injuring 110.
He blamed airport officials for "clear security breaches", and called for sackings if negligence was proved.
Militant groups from the North Caucasus are suspected of planning the attack.
Speaking to security officers in televised remarks, Mr Medvedev said terrorism was the most serious threat facing Russia today.
He called for those responsible to be hunted down and their organisations "eliminated", Kazinform refers to BBC News.
Prime Minister Vladimir Putin also took a hard line, saying that "retribution is inevitable".
"This was an abominable crime in both its senselessness and its cruelty," he said, offering government help to the families of those affected.
Airport defiant
In a hard-hitting verdict on the events at Domodedovo on Monday, Mr Medvedev said "pure anarchy reigned" at the airport.
"People were allowed to walk in from anywhere. The entrance restrictions were partial at best."
He said an investigation by the prosecutor general would establish whether transport officials were guilty of criminal negligence.
In the meantime, he ordered the interior ministry to propose dismissals or reassignment of transport officials, RIA Novosti news agency reported.
Describing the terror threat in Russia as being higher than that in the US, Mr Medvedev said a system of "comprehensive checks" based on Israeli and US security procedures should be introduced at all transport hubs.
Airport authorities firmly denied any culpability.
"We fully met all the requirements in the sphere of air transport security for which we are responsible," spokeswoman Yelena Galanova said.
