The Kurdish YPG (or People’s Defense Units) has released a summary of its operations for 2015. The YPG claims to have killed nearly 6,000 “enemy” fighters, most of whom likely belonged to the Islamic State, while losing just 680 of its own members in combat. The statistics provided by the YPG imply a kill ratio of nearly 9 to 1, which obviously seems high.
Kurdish forces have entered the Iraqi town of Sinjar, which was seized by the Islamic State in August 2014. The offensive in Sinjar is part of a broader operation intended to disrupt the Islamic State’s supply lines running from Iraq into Syria.
