Libya's internationally recognized army declared a a cease fire, according to an AFP report.
"We declare a ceasefire from midnight (2200 GMT) Sunday," said the army said, stressing however that it would continue to pursue "terrorists", as UN-brokered peace talks resume in Geneva next week.
The army also said it would monitor the situation on ground "to prevent any change in front lines or transportation of weapons and ammunition," which it would consider a violation of the truce.
Soldiers "have been given the right to defend themselves if they come under fire," the statement added.
The cease fire follows a truce by an Islamist backed rebel group.
On Friday, the Fajr Libya (Libya Dawn) militia alliance said it had agreed to "a ceasefire on all fronts" in the North African country on condition that "the other parties respect the truce".
It also pledged to open up "safe passages to channel humanitarian aid", especially in Libya's battleground second city of Benghazi.
Since Muammar Gaddafi was overthrown in 2011, a power vaccume has left Libya bitterly embroiled in violence.
