FBI arrests woman for allegedly promoting ISIS-inspired attacks

Just days before the fifteenth anniversary of the Sept. 11, 2001, attacks, federal authorities have arrested a Kentucky woman who allegedly advocated online for terrorist attacks in the U.S. and promoted ISIS propaganda through her social media accounts, according to sources familiar with the matter.

The FBI arrested the woman, who is in her 50s, overnight, and she is expected to appear in federal court later today, sources said.

An arrest usually indicates charges have been filed in some form, but it's unclear when or how charges would have been filed in this case. Defendants in similar cases often face charges of providing material support to a terrorist group.
