The UN has presented a draft proposal for a Libyan unity government to warring factions in an attempt to stabilise the conflict-torn country, the BBC reported.

The plan unveiled at talks in Morocco on Monday addresses terms of a truce and disarmament of armed groups.

UN special envoy Bernardino Leon urged the Libyans to back the proposal.

Since the overthrow of Muammar Gaddafi in 2011, Libya has descended into chaos and seen jihadist groups fighting for control of the oil-rich nation.

Islamic State (IS) militants have recently managed to gain a foothold in Libya's cities of Derna and Sirte.
