Russian media reports say the death toll from the twin suicide bombings in the Moscow subway rose to 40 today after a 51-year-old man died in hospital.

Another 84 people injured in the March 29 attacks remain in hospital.

Two days after the Moscow bombings, 12 people were killed in two suicide bombings in the North Caucasus republic of Daghestan.

Russian media earlier today said investigators had identified one of the female suicide bombers who carried out the Moscow attacks as the teenage widow of a Daghestani militant.

The reports -- which have not been officially confirmed -- named the woman as Dzhennet Abdurakhmanova, the 17-year-old widow of a Daghestani Islamist rebel killed in 2009, Umalat Magomedov.

Chechen rebel leader Doku Umarov has claimed responsibility for the Moscow bombings.

President Dmitry Medvedev, meeting with political parties leaders today, said investigations into the attacks were proceeding quickly.

Medvedev, who visited Daghestan on April 1, described the situation there as "stable and calm."
