Egyptian President Abdel Fattah el-Sissi, the new chairman of the African Union, at the 32nd African Union Summit, in Addis Ababa, February 10, 2019.
Military sources within the United Nations-backed Government of National Accord (GNA) said the jet operated by the self-styled Libyan National Army (LNA) was downed on Sunday in Tripoli's southern outskirts, as fighting for control of the capital rages.
Since the overthrow and death of dictator Muammar Gaddafi in 2011, Libya has been ruled by rival administrations in the east and west of the vast, oil-rich country.
Haftar, who casts himself as a foe of "extremism" but is viewed by opponents as a new authoritarian leader in the mould of Gaddafi, has vowed to continue his offensive until Libya is "cleansed" of "terrorism".More news: 'Game of Thrones' Cast Salaries: See What the Stars Make!
Egypt has supported Gen Haftar's drive against Islamic militants in the east and south of its western neighbour, reportedly providing both funding and arms to his LNA.
The presidency released photos showing Haftar, dressed in a blue suit, sitting with Sisi and his head of intelligence Abbas Kamel.
"The forces of the Libyan army shot down an enemy plane that was preparing to conduct air raids in the Wadi al-Rabie area", Government of National Accord spokesman Mohamed Gnounou told AFP.
"Our position will not change", United Nations envoy Ghassan Salame tweeted. "No matter how obstinate one becomes, there is no solution except a political one".More news: ‘Titans’ adds ‘Game of Thrones’ actor Iain Glen as Bruce Wayne
At least 121 people have died in clashes between rival militias fighting for control of Libya's capital, the World Health Organization (WHO) said on Sunday.
Haftar has defied worldwide calls to halt his battle against fighters loyal to the UN-backed Government of National Accord based in Tripoli.
The "life goes on" attitude of some overseas Filipino workers (OFWs) in Tripoli may soon be in peril with the further escalation of clashes between factions in Libya, following reports that foreign governments will soon be sending support for military strongman Khalifa Haftar.
While some pro-Haftar media had predicted a quick victory, Tripoli government forces have halted him about 11 km (7 miles) from the center near an airport that was largely destroyed in a previous bout of fighting five years ago.More news: The BTS & Halsey Collab Is a Total BOP
