A prominent Russian newspaper says investigators have identified a teenager as one of two suicide bombers responsible for Monday's attacks that killed 39 people in two Moscow subway stations.
Kommersant said Friday 17-year-old Dzhennet Abdurakhmanova, the widow of a slain Caucasus militant, was one of the bombers.
The newspaper published a photograph of the young woman in a Muslim headscarf with her late husband Umalat Magomedov.
The Kommersant reports authorities have not yet officially identified the second bomber, but she is believed to be 20-year-old Markha Ustarkhanova from Chechnya. Ustarkhanova is the widow of a Chechen militant who was killed last year while allegedly preparing for an assassination attempt on Chechen leader Ramzan Kadyrov.
