Wenza Ali Mutlaq walked a bit uncertainly up the long street near the main government offices here on June 22, the hot wind stirring her heavy black abaya. She passed the concrete barricades put up to ward off suicide car bombers and made her way alone, almost haphazardly.<\/p>\n
Suddenly, a police car zoomed in. A policeman got out to talk with her. And then their lives were over \u201d\u201d torn apart, along with 14 other people, by the huge blast of fire from her concealed explosive vest.<\/p>\n
Ms. Mutlaq, who was in her 30s and whose attack was captured on a security video, was the 18th female suicide bomber of the war to strike in Diyala Province, which has been hit by female attackers much more frequently than any other province of Iraq, according to Iraqi police records and the American military. So far, 11 of the 20 suicide bombings carried out by women in Iraq this year have occurred in Diyala.<\/p>\n
Why so many women? Why now? In a particularly painful twist, the phenomenon seems to have arisen at least in part because of successes in detaining and killing local members of Al Qaeda in Mesopotamia, a homegrown Sunni insurgent group that American intelligence officials say is led by foreigners.<\/p>\n
