An American man has been killed in Syria, a State Department spokesman said on Wednesday, declining to provide details.
Department spokesman Jeff Rathke identified the American as Keith Broomfield.
NBC News reported Broomfield was in Syria fighting alongside Kurdish forces against Islamic State militants. Reuters could not immediately confirm why Broomfield was inSyria.
Social media accounts belonging to Kurdish fighters reported Broomfield's death, saying he was killed near the border town of Kobani, NBC said. It added that the Kurdish forces, known as the Kurdish People's Protection Union or YPG, have not officially confirmed the death.
NBC said one Kurdish official told the news network that an American who had joined Kurdish fighters died fighting Islamic State but declined to give a name.
The report also cited Broomfield's mother in Westminster, Massachusetts, who said she learned of his death from his brother and that Broomfield had left for Syria four months ago.
