American woman killed in Syria ID'd by relatives as Nicole Lynn Mansfield

(CNN) -- An American woman killed in war-torn Syria has been identified as Nicole Lynn Mansfield, 33, of Flint, Michigan, her aunt and grandmother told CNN.

The grandmother told CNN that FBI personnel came to her home to talk about reports of her death. The relatives confirmed the identity Thursday night after they saw images of the woman online. The FBI and the State Department have not officially confirmed the identity.

Syrian state-run television reported Thursday that forces loyal to President Bashar al-Assad killed three Westerners and identified the woman -- releasing what it claimed were images of her Michigan driver's license and U.S. passport. It also released what is said was the name and passport of a British citizen. It did not identify a third person who it claimed was a Westerner.

The news outlet claims they were fighting alongside the rebels and were found with weapons. The report said the three were ambushed in their car in the flashpoint province of Idlib in northwestern Syria, where government forces have been battling rebels for control.
