British Ambassador to Russia Anne Pringle lays flowers in memory of those killed in Monday's bomb explosion at Moscow's Domodedovo airport January 26, 2011. Prime Minister Vladimir Putin said on Wednesday that those behind a deadly suicide attack on Russia's busiest airport were unlikely to be from Chechnya, but analysts and media said North Caucasus militants were to blame.
