Veteran Libyan military commander Khalifa Haftar returned to Benghazi on Thursday after a two-week absence for medical treatment in Paris, according to a statement posted on a social media account used by his forces.
Haftar, 75, was greeted by a delegation of senior officials after landing on a late afternoon flight from Cairo, according to the statement, posted on the Facebook account of Haftar's Libyan National Army (LNA).
No pictures or footage of Haftar's arrival were immediately released.
News that Haftar had been treated at a Paris hospital had triggered fierce speculation over his condition.
Haftar's Libyan National Army (LNA) is aligned with a parliament and a government that has been based in eastern Libya since 2014.
They control most of eastern Libya, including the majority of its oil fields and ports, as well as parts of the south.
LNA spokesman Ahmed al-Mismari said that on his return Haftar would take part in celebrations marking the anniversary of his "Karama" (Dignity) campaign, the military operation he started in 2014 to drive Islamist militants and other opponents out of Benghazi.
Haftar declared victory in July 2017, though sporadic fighting continued until late last year.
