The Islamic State-- formerly Islamic State of Iraq and al-Sham (ISIS)-- has previously used water as a destructive tool to destroy crops and dams in Shi'ite territory. Now, ISIS is attempting to deprive major Christian strongholds of water through their control of pipe systems. According to Bloomberg Businessweek, the city most affected by ISIS's new campaign to deny water to as many Christians and Shi'ites in Iraq as possible is the city of Qaraqosh, currently under control of Kurdish Peshmerga forces and, thus, impenetrable to the terrorist jihadist group.
