The government of national unity in Libya says it has carried out air strikes against criminal gangs involved in trafficking people, drugs and fuel.
Residents in the western city of Zawiya said they heard explosions.
It has seen sporadic clashes between factions that back and oppose the Tripoli-based administration, which is one of two rival governments in Libya.
It’s not known to have any air force of its own, but has used drones belonging to its Turkish military allies in the past.
Libya remains in political chaos after the failure of a UN-backed process to unify its divided factions last year.
