Daily Beast – With ISIS’s brutal murder of Peter Kassig, a 26-year-old American aid worker who dedicated his life to the plight of Syrian refugees, the militant group has one more U.S. citizen remaining in its clutches, according to current and former U.S. officials, as well as individuals involved in efforts to free the Americans.

The hostage is the only American woman held by the militant group. She is the same age as Kassig, and, like him, was kidnapped while trying to help people whose lives have been upended by the long Syrian civil war. She was particularly moved to help children who have been orphaned and separated from their families. The woman was taken in August 2013, along with a group of other aid workers who have reportedly been released.
