Talks in Moscow about bringing an end to Libya’s long-running civil war have been adjourned for the night after the country’s rival governments on Monday considered ceasefire proposals from Russia and Turkey.

Fayez Sarraj, the head of Libya’s U.N.-recognized government in Tripoli, and his rival Khalifa Hifter met with top diplomats and military officials from Russia and Turkey for the talks that lasted about seven hours. The negotiations were held behind closed doors, and Sarraj and Hifter didn’t meet directly. A tentative truce came into force on Sunday.
