Dmitry Medvedev seeks security shake-up after Moscow airport bomb

Russian President Dmitry Medvedev has blamed airport officials for "clear security breaches" and called for sackings if negligence is proved following a suspected suicide bombing at Moscow's Domodedovo airport which killed 35 people and injured 110.

Militant groups from the North Caucasus are suspected of planning the attack on Monday.

For years the centre of this insurgency was the republic of Chechnya.

But it is thought that extremist cells are also now operating from nearby Ingushetia and Dagestan.
