Institute For The Study Of War reports: The Islamic State of Iraq and al-Sham (ISIS)’s affiliate in Libya lost control of its eastern stronghold of Derna after tensions with a local Islamist militia escalated into violent conflict on June 9, 2015.

The Mujahedeen Shura Council of Derna (MSC Derna), an umbrella group controlled by ASMB, released a statement declaring jihad on ISIS in Derna soon after the assassination. Clashes erupted across the city.
