Russia Fears More Attacks by 'Black Widows'

The Moscow subway bombing might just be the beginning of a campaign of suicide attacks—investigators say that up to 19 trained suicide bombers from the same terrorist cell as the subway attackers remain at large. The bombers likely belonged to a 30-person, all-female "martyrs' brigade" led by the late Chechen terrorist Said Buryatsky, known by the media as "the Russian Bin Laden."

Buryatsky was killed by Russian forces earlier this month. Of the original 30, 11 bombers have carried out their missions, leaving 19—all likely filled with thoughts of revenge after the killing of their boss. The terrorists are called "black widows" because they often have lost husbands, fathers, or brothers in violence with Russian forces, the Telegraph reports.
