(VOVworld) - Libyan political leaders reached a new version of a UN-brokered peace deal Saturday, putting pressure on the Tripoli leadership to sign on and build a unity government in hopes of ending the country's chaos.

Bernardino Leon, the UN envoy for Libya, considered the move an important advance toward a final peace accord.

The UN-backed deal was supported by the internationally-recognized House of Representatives of Libya which is based in the port city of Tobruk, local and regional leaders, and civil social organizations.

But a key player - the General National Congress (GNC), the legally installed government in Tripoli - and its allied Libya Dawn militia were not part of the agreement.

Negotiators plan to meet again after the Ramadan holiday to work on forming an interim government and finalizing a power-sharing agreement.
