The New York Times reports that the Domodedovo Airport bomber has been identified as a 20-year-old from the North Caucasus; apparently 32-year-old Vitaly Razdobudko, who was considered in some quarters to be the prime suspect, has been ruled out due to DNA evidence.  Russia has apparently introduced a color-coded alert system akin to that employed in the United States after 9/11.  The investigative committee has stated that the attack’s location was chosen precisely because the bomber was targeting foreigners.  ‘When Moskovsky Komsomolets surveyed its readers on Jan. 27, 41% of Muscovites responded that the terrorist attack at Domodedovo was most likely organized by the country’s own siloviki’.  Medvedev had a hard time selling his ten Davos principles under the circumstances, argues the New York Times.  ‘Security systems cannot work in a country rotten with corruption’, says Elena Panfilova, director of Transparency International in Moscow, in a piece from Newsweek on the failings of Putin’s counter-terrorism measures.  An increase in Slav-Islamic terrorism prompted by poor standards of living in Russia is particularly alarming for the Kremlin, argues the Telegraph.   Following the spate of post-bombing firings, President Medvedev has appointed Russia’s road police chief as deputy interior minister responsible for transport security.  As fears that the Sochi Olympics will be a terrorist target mount, the Kremlin has pledged that it will spend $2 billion on security measures.
