A woman who was among those wounded when a female suicide bomber blew herself up in the southern Russian region of Dagestan has died.

Police and doctors said Sunday the 37-year-old woman was the only one to die, other than the suicide bomber, but that several others remained hospitalized in serious condition.

Saturday's attack wounded at least 17 others, including two children and five police officers. Police later identified the attacker as the widow of two Islamic militants killed by security forces.

Dagestan remains an epicenter of violence in the confrontation between Islamic extremists and federal forces.

Tamerlan Tsarnaev, one of the two brothers suspected of carrying out the Boston Marathon bombings, spent six months in Dagestan in 2012.
