Damascus: A raid by US-led forces in northwestern Syria Friday killed a senior member of Islamic State militant group, the US military said. US Central Command said it had killed IS member Dhiya Zawba Muslih al-Hardan and his two adult sons, who were also affiliated with the group, early Friday in a raid in the town of al-Bab, in Syria’s Aleppo province. It said the men “posed a threat to US and Coalition Forces, as well as the new Syrian Govt.” The Syrian Observatory for Human Rights, a UK-based war monitor, said the raid was carried out through an airdrop of forces, and that ground forces from the Syrian govt’s forces and the Kurdish-led Syrian Democratic Forces participated.
