Father identifies suicide bomber

A 28-year-old computer science teacher has been identified by her family as the second of two female suicide bombers who killed dozens of people on the Moscow metro a week ago, according to a Russian newspaper.

Rasul Magomedov told Novaya Gazeta he had recognised his missing daughter Maryam after being shown photos of the remains of the unidentified suicide bomber.

He said his daughter graduated from the Dagestan Pedagogical University in 2005, before returning to her village to teach. "We cannot even suggest how Maryam could get to Moscow. Yes, she was religious. But she never expressed any radical beliefs," he said.

More than 50 people have been killed in suicide attacks in Russia in the past week, both in the Moscow metro by bombers the Russian media have dubbed "Black Widows", and in a town in the North Caucasus region of Dagestan. Fears of a new bombing campaign increased after a double bomb attack on a railway line yesterday which security forces said was linked to the metro attacks.
