The management at Russia's Domodedovo Airport is being held responsible for allowing a suicide bomber to carry out a devastating attack there on Monday. President Dmitry Medvedev says it was poor attention to security which led to the blast at the country's biggest airport. The suspected suicide bomber killed 35 people and left around 180 injured. The explosion, which took place in the international arrivals area, is Russia's worst terrorist atrocity since twin bombings rocked Moscow's metro system last March. Around a hundred people caught up in the airport blast are being treated in hospitals across the capital.
