The Islamic State militants have abducted some 900 Kurds in the northern Syrian province of Aleppo over the past three weeks amid fierce fighting for control of a nearby IS stronghold, a Kurdish official and Syrian activists said Friday.
The abductions began shortly after the predominantly Kurdish and U.S.-backed Syria Democratic Forces began an offensive on May 31 to capture the IS stronghold of Manbij from the extremists.
The extremist group has a history of mass kidnappings in areas they control in Syria and Iraq and have mostly targeted Christians and Kurds in the past.
