WASHINGTON (AP) - As it looks to expand its territorial base across broad swaths of Iraq and Syria, the Islamic State group is recruiting for more than just fighters.
The extremist organization also has been targeting its sophisticated propaganda to entice potential wives and professionals such as doctors, accountants and engineers in its efforts to build a new society.
Among those it has lured were three teenage girls from Colorado, who set out for Syria this fall after swapping Twitter messages about marriage and religion with IS recruiters, and a young woman who sought to fight there - or failing that, to use her nursing skills. It's a diverse pool of recruits whose motives perplex Western governments seeking to combat the flow.
The group "is issuing a bit of a siren song through social media, trying to attract people to their so-called caliphate," FBI Director James Comey told reporters. "And among the people they're trying to attract are young women to be brides for these jihadis."
The group conscripts children for battle, recruits Westerners for acts of jihad and releases videotapes of beheadings. But it also uses propaganda with a humanitarian appeal, such as photos of bombed-out Syrian villages coupled with pleas for help. Video images of smiling children being given treats and enjoying stuffed animals paint a family-friendly portrait that suggests roles within the proto-state for wives and mothers.
Even as they preach violence, "they'll do the warm and fuzzy ... the gun in one hand and the kitten in the other," said Assistant Attorney General John Carlin, head of the Justice Department's national security division.
"They're seducing them with promises about how wonderful it will be," said Mia Bloom, a professor of security studies at the University of Massachusetts Lowell. "They promise a sense of adventure, that their worries will be addressed."
Justice Department officials say people aiding the Islamic State understand what they're getting into and risk prosecution, whether or not they venture to Syria and even if they don't plan to take up arms themselves. Prosecutors have criminally charged more than 15 people in connection with supporting Islamic militant groups.
A Rochester, New York, food store owner stands accused of trying to arrange for others to travel to Syria and of plotting to kill members of the U.S. military. An Illinois man, allegedly determined to join militants, left behind a letter saying he was disgusted by Western society. And prosecutors say a North Carolina man asked Allah online for martyrdom.
Most charges are brought under a statute that makes it illegal to provide "material support" - including money, training or a false identity - to a designated terrorist group. Defense lawyers argued the law is overly broad and ensnares the misguided as often as it sweeps up the dangerous. Courts, however, have accepted an expansive interpretation of the law.
"We need to make clear that if you want to go over there and join a terrorist group, you're likely to end up instead in jail," Carlin said.
Justice Department officials say they're also trying strategies other than prosecution, including trying to identify potential recruits before they go.
Perhaps no case better shows the penetration of the recruitment campaign than that of the three Colorado girls, all from East African immigrant families, who were radicalized online and headed for Syria in October.
A review of the girls' social media use, which included thousands of Twitter messages and postings on other sites, by the SITE Intelligence Group shows they were in contact with online jihadists from around the world and were deeply interested in marriage and the role of women. As recruiters interacted with the girls, their typical teenage banter about friends and school became replaced with discussions of religion, paradise and death, the review showed.
Six months before they went overseas, one girl wrote that she wanted to get married as soon as possible and her friends wished her well, telling her they hoped she got an "amazing husband because you do not deserve anything else!"
