TRIPOLI/ROME: Lawmakers from Libya’s two rival parliaments have signed a declaration of principles aimed at ending the North African country’s civil conflict.

The proposal was signed late Saturday by two groups from the Libyan parliament and the rival General National Congress. The initiative is separate from U.N.-sponsored talks between the country’s two competing governments and parliaments to form a united administration.

Four years after the fall of Moammar Gadhafi, Libya is in turmoil. Tripoli has been controlled since last year by an armed faction called Libya Dawn, forcing the internationally recognized government and elected parliament to work in the east.

Lawmakers said the declaration calls for forming a 10-person committee – five members from each parliament – that would be charged with naming an interim prime minister and two deputies. Legislative elections would be held within two years.

Delegates from the elected House of Representatives and the GNC said it was too early to decide on the proposal, which would have to be put to both houses for a vote.

Western governments are pushing for the U.N.-backed agreement to form a government of national unity as the only way to end the chaos in Libya, where Daesh (ISIS) militants have gained ground.

Moderates have supported the U.N. proposal after a year of talks, but hard-liners in both camps have been demanding more concessions from the other side.

The U.N. proposal calls for an executive six-member presidential council that would try to represent Libya’s traditional regional power bases, along with the House of Representatives congress and a second advisory chamber State Council.

NATO chief Jens Stoltenberg said in an interview published Sunday that NATO is ready to help a future national unity government.

“If a national unity government is formed, we are ready to help it and provide assistance,” Stoltenberg said in an interview with Italy’s Repubblica and several other EU dailies ahead of an international conference on Libya in Rome next Sunday.

However, “we are not discussing a major new military operation in Libya, and I will not be recommending it,” he said.

Former colonial power Italy will host the Dec. 13 conference which is aimed at preventing Libya’s total collapse and halting the advance of the extremist Daesh.
