Pope Francis offered his full support for UN efforts to end the conflict in Libya and the global war on Syria in his Christmas message on Friday.

"We pray... that the agreement reached in the United Nations may succeed in halting as quickly as possible the clash of arms in Syria and in remedying the extremely grave humanitarian situation of its suffering people," he said.

"It is likewise urgent that the agreement on Libya be supported by all, so as to overcome the grave divisions and violence afflicting the country."

The UN Security Council last week unanimously adopted a resolution endorsing a proposed peace plan to bring the Syrian national representatives and opposition factions and armed groups together for talks in January.

The plan followed nearly two months of strenuous efforts among top diplomats from 17 countries, including Russia and Iran.

Syrian Foreign Minister Walid al-Moallem said Thursday the country was ready to take part in new talks in Geneva aimed at ending the war, though it appeared to make its participation conditional on which opposition groups attend.

On Wednesday, the UN Security Council gave its backing to the new national unity government in embattled Libya, a move it hopes will help stem mass migration to Europe and reverse gains made by terrorists of the so-called 'Islamic State of Iraq and the Levant' (ISIL) takfiri group.

The 15-nation council gave its support to the deal signed last week in the Moroccan town of Skhirat between representatives of strife-torn Libya's two competing governments.
