Russian authorities say the death toll from last month's bombing at Moscow's Domodedovo airport has risen to 36. A spokesman for Russia's Health Ministry today said a victim who was in critical condition has died. According to Russian investigators, the suicide bomber was a 20-year-old man from the volatile southern Caucasus region. Prime Minister Vladimir Putin has said the early investigation showed no connection to Chechen extremists. The bombing was the worst in the Russian capital since last March when a double suicide bombing killed at least 40 people in the Moscow subway.
