Hoda Muthana, an ISIS bride who was denied a request to return to the United States, is one of hundreds of Americans who have tried to join ISIS since 2011.While the majority of the recruits are men, many women have traveled or attempted to travel to Syria to fight for ISIS or wed ISIS fighters.An American woman fighting for ISIS was the first American killed in the Syrian conflict in 2013.The whereabouts of some of the women are unknown, and others, including three teens from Colorado, were stopped by police before they could make physical contact with ISIS.The State Department announced on Wednesday that a US-born woman who left Alabama to join the Islamic State would not be welcomed home. Secretary of State Mike Pompeo said that Hoda Muthana "does not have any legal basis, no valid US passport, no right to a passport, nor any visa to travel to the United States."But she's not the only American woman who has traveled to Syria further the ISIS cause. Muthana is one of hundreds of Americans who have attempted to join the Islamic state and other radical Islamist groups, according to a recent report from George Washington University's Program on Extremism.Of the 300 attempts, the report names 72 Americans who have successfully traveled to Syria or Iraq and joined ISIS and other jihadist groups since 2011. Just 12% of the travelers have been women.In recent weeks, several women from across the world who are now living in Syrian refugee camps have identified themselves as ISIS brides, asking to return home to the US, Europe, and Canada.Audrey Alexander, the author of the GWU Program in Extremism's report "Cruel Intentions: Female Jihadists in America," told INSIDER that while many of the women have different motivations for joining extremist groups in Syria and Iraq, many marry ISIS fighters for safety and security while building the Islamic State.Read more: ISIS brides from Canada, the US, and Europe are asking to return home years after fleeing for Syria. Here are their stories."Once youre in ISIS-controlled territory, being married brings you security, money, goods, status, and treatment. So there are real incentives to be married while youre there," she said, adding that being married is one of many auxiliary roles many women have in the society, like raising children and running social media pages."What women want to do there, and what the mission is, is to create an Islamic State," Alexander said. "And women's roles in that is to serve in a domestic role in some capacity, but it's really a broader state building effort, an experiment in so many ways."Alexander's report profiles several women who moved or attempted to move from the US to join ISIS in Syria and Iraq. Some of the women moved to the countries with their husbands, while others went alone.At least one woman has died, two have been sent to jail, one is begging to return to the US, and the whereabouts of others remain unknown.Here are some women's stories.Hoda Muthana left Alabama for ISIS in December 2014, and is now asking to return.Hoda Muthana was 19 when she left her home in Alabama to join ISIS in Syria in November 2014.She was radicalized online, according to a 2015 BuzzFeed report, andused a phone given to her by her father to access conservative Islamic lectures online.Once in Syria, she started a popular Twitter account where she made violent calls to action.One tweet read: "Go on drive bys, and spill all of their blood, or rent a big truck and drive all over them.
