Key militias in the Libyan capital, Tripoli, have announced that they are uniting to form a joint force.

The new grouping, dubbed the Tripoli Protection Force, will bring together some of the city’s most influential militias which are aligned with the UN-backed government, including:

The Tripoli Revolutionaries
Nawasi Battalion
The Abu Salim Joint Deterrence and Intervention Force
The Bab Tajoura armed group.

This is according to a document signed by the groups and released on Tuesday.

The merger comes as the government continues its efforts to implement new security arrangements in the city after deadly militia clashes killed at least 120 people in August and September.
