Abu Salim Martyrs Brigade

The Abu Salim Martyrs Brigade is an Islamist militia that advocates the implementation of Sharia law within Derna, Libya. The group is known for enforcing strict social rules in the city.

Background
The Abu Salim Martyrs Brigade was created by former Libyan Islamic Fighting Group member Abdel-Hakim al-Hasidi. Following the Libyan Civil War, the brigade was taken over by Salim Derby.

In 2014, the Islamic State of Iraq and the Levant (ISIL) in Libya took over much of Derna. Abu Salim and ISIL repeatedly clashed in the following months in disputes over power and resources. Derby was killed in fighting with ISIL militants in June 2015.
