A raid by U.S. forces and a local Syrian group aimed at capturing an Islamic State group official killed a man who had been gathering intelligence against IS, according to family members and Syrian officials. The operation, conducted in October in Dumayr, Syria, did not yield the expected IS official, and U.S. Central Command provided no public statement about the outcome of the raid. Initial media reports suggested the raid captured an IS official, but subsequent accounts dispute that narrative, indicating the person killed was working undercover for the Syrian security services and had cooperated with the interim Syrian government in security efforts against IS. The incident highlights the fragile and overlapping security arrangements in Syria as the U.S. coordinates with local and Syrian authorities in the fight against IS remnants.
