TRIPOLI: Libya forces loyal to eastern-based commander Khalifa Haftar announced on Saturday a ceasefire starting 00:01 a.m. on Sunday Jan. 12 conditional on acceptance by their rivals, spokesman Ahmed Mismari said in a statement.

Turkey and Russia urged Libya's warring parties on Wednesday to declare a ceasefire on Sunday amid clashes and air strikes in a conflict drawing increasing foreign involvement and concern.

Turkey backs Fayez Al-Serraj's Tripoli-based National Accord (GNA), while Russian military contractors have been deployed alongside General Khalifa Haftar's eastern-based Libyan National Army (LNA).

Earlier on Saturday, Germany's chancellor Angela Merkel said Berlin would host a Libya peace summit, following a meeting in Moscow with Russian president Vladimir Putin.

Putin had also said the time had come for peace talks on the Libyan crisis, adding that it was important that the conflict in the country was ended.
