A Russian woman who converted to Islam from Christianity in 2007 walked into the home of a cleric three months ago and blew herself and seven others to bits.
The woman, Aminat Kurbanova, had been raised a Christian and was introduced to Islam in 2006 by her brother-in-law, Rustam. Shortly thereafter, both she and her husband Marat converted to Islam.
Then the death began.
In 2008, Rustam was killed in a police raid on suspected radicals. 12 months later, Marat was killed in a car on which police opened fire. And Marat's other brother, Ali, vanished after allegedly being dragged away by police.
Kurbanova remarried but left her husband in March of this year amid fears of abuse. Then, three months ago, she walked into the home of cleric Sheikh Said Atsayev and did the deed.
Islamists have carried out more than 19,000 deadly terror attacks around the world since the 9-11-2001 attacks in the United States. Like Aminat's suicide bombing, many of these target other Muslims.
