The United Kingdom on Tuesday expressed concern over the violent clashes that rocked districts of Tripoli late on Monday.
The fighting broke out after the RADA Deternce Force detained Mahmoud Hamza, a military commander leading another powerful military faction.
The British Embassy said the UK is "deeply concerned to see violent clashes in Tripoli," underscoring that protecting civilian lives is paramount.
Earlier, the Head of the UN Support Mission in Libya urged the conflicting parties to de-escalate the violence and respect the demands of the Libyan people for peace and stability.
The British embassy said its government echoes the UNSMIL call for all sides to de-escalate immediately and engage in dialogue.
