The father of a 28 year old teacher in Dagestan is reported to have recognised his daughter from images shown of the bomber in the media. DNA test is now pending to confirm that. The man told the media that there were rumours his daughter was secretly married to a militant leader, but that she denied it. RT looks at how suicide bombers are becoming a lethal weapon of terror.
