The suicide bomber who killed 35 people in an attack on a Moscow airport earlier this week was a 20-year-old man from the North Caucasus, investigators said Saturday. According to dpa, the mangled body of the man had been identified, a spokesman for the national investigative committee told the news agency Interfax, though he did not give a name. The case had been solved and further suspects were being sought, the spokesman said. About 180 people were injured in Monday's attack at Domodedovo airport, Moscow's busiest, dozens of whom were still being treated in hospital.
